This Week on perl5-porters - 14-20 June 2008 David Nicol: Does pushing all exceptions to @@ whenever $@ gets assigned to break anything?Abigail: In theory, it could, as @@ is a "normal" array that can be used as such. But I doubt anything serious will break. I'd say anyone that uses a punctuation variable that currently has no special meaning does so at his/her own risk, and doesn't have the right to complain if it does get special meaning.-- Abigail, suggesting that a little backwards compatibility breakage from time to time can be good for the soul.

This Week on perl5-porters - 1-6 June 2008 Traditional exception handling is more like equipping each Klingon with a dead-man's switch attached to a nuke. Dying by accident in someone else's nuke blast would be a death without honor. So the point of the Perl 6 exception model is to try to keep as many warriors alive as long as possible in order to inflict the maximum possible damage on the enemy, which is our highest goal, after all. :) -- Larry Wall, on the issue of dealing gracefully with errors.

This Week on perl5-porters - 18-24 May 2008 "Ah, more details about filenames. Well, this sounds positively weird. Octet strings are not particularly user-friendly if you can't interpret them as characters reliably. From what you say, and what I think I've heard elsewhere, Unix filename interpretation is a mess. Seems like the only bigger mess I've heard about is VMS file handling, where they seem to have a choice of several messes." -- Glenn Linderman, deep in the heart of Unicode, case conversion, filenames, encodings, character sets, ß and other exciting issues.

This Week on perl5-porters - 4-10 May 2008 Today, I was doing some mucking about with class data, generated packages, and Class::ISA, and I started to wail and gnash my teeth. I cried, "Why can't I just replace the darn object system?" -- Ricardo Signes, a man with a method.

I've been playing around with MAD this morning [...] The current state of the tests for MAD is a bit sad, though I hope to have something that will make interested porters glad in the near future. -- Jesse Vincent, not a bad lad to spend a tad on MAD. (gad, Dad! it's not a fad).

This Week on perl5-porters - 6-12 April 2008 David Nicol: I have no idea what NaN(Q) is by the way; Google suggests it is a furniture store in Japan. Jarkko Hietaniemi: It's the strong, silent type of NaN. As opposed to the hysteric, screaming type of NaN (aka NaNS). -- David N. and Jarkko H., arcing tangents.

This Week on perl5-porters - 23-29 March 2008 "Anyway, a lot of these design changes work together to produce a smoother result. I confess I haven't thought much about whether they could be borrowed piecemeal; I have a hard enough time keeping one fantasy language in my head at a time." -- Larry Wall, on the differences in exception handling between Perl 5 and Perl 6.

This Week on perl5-porters - 9-15 March 2008 "Take our command, strip off the package, pass the short name and the calling package to _make_fatal(), and then use magic-goto to call our subroutine at the end. It's simple, right? Yet I struggle to find any time when it's correct." -- Paul Fenwick and his Fatal attraction.

This Week on perl5-porters - 10-16 February 2008 "So should we punt in this case and revert to the old warning for SvGAMAGICAL? My personal opinion is to leave it. People doing strange things should not be surprised by strange results." -- Rick Delaney, debating the Principle of Least Surprise (or something like that).

This Week on perl5-porters - 27 January-2 February 2008 "It's a very naive implementation [...]. Given the scary comments Nicholas added in that code, I'd be grateful to see whether one can come up with a case where that breaks" -- Rafael Garcia-Suarez, warning about warning about undef.

This Week on perl5-porters - 30 December 2007-5 January 2008 That's now twice in this thread that I've been accused of favouring languages that I actually dislike [...] . I think the Java model of exception signatures is awful. -- Zefram (I hope you know this will go down on your permanent record).

This week on the Perl 6 mailing lists "The current pugs implementation is just translating to the old form underneath, so it's not surprising it's a bit off. That's the sort of thing that happens when the language designer gives the language implementor whiplash. However, I rather suspect the interpersonal metaphorical meaning was lost on the physicist/comic who decided that the 3rd derivative of position should be called 'jerk'. :)" -- Larry Wall, in 'What should file test operators return?'

This week on the Perl 6 mailing lists Due to a lack of free time, I will be unable to continue creating the Perl 6 summaries after April. We are looking for a volunteer or group of volunteers to take over the task. Please contact me if you would like more information about what the job entails (contact information can be found at the end of this post).

This week on the Perl 6 mailing lists "It seems you are presuming a Waterfall model of development here. We're not doing the Waterfall, we're doing the Whirlpool, where the strange attractor whirls around with feedback at many levels but eventually converges on something in the middle. In other words, a whirlpool sucks, but the trick is to position your whirlpool over your intended destination, and you'll eventually get there, though perhaps a bit dizzier than you'd like." -- Larry Wall, in 'What criteria mark the closure of perl6 specification'

This week on the Perl 6 mailing lists "'Course, if someone goes ahead and adds the Y combinator, one must naturally begin to wonder what the YY combinator would be... :-) " -- Larry Wall "Obviously it generates a function so anonymous that it can't even refer to itself. I call it the depressed existentialist solipsist operator." -- chromatic, in 'Y not'
