in thread while(<>) { ... } considered harmful

I disagree with saying that map is considered harmful. As I noted in other reply in this thread its behaviour is consistent with other Perl operators: for/foreach and grep. In my opinion it is while(<>)'s magic is wrong. It should localize $_ so it doesn't affect outer scope.

[marto]: hopefully next year I'll be in a position to go to Perly things in Europe :)
[Corion]: Maybe I'll use the Real Jekyll a bit to get a feel for how it actually works, and to get annoyed by it ;)
[Corion]: marto: That would be cool :) There is no kids care at Perly events unfortunately, so it's not entirely family friendly
[Corion]: I think I should define a set of (say) five projects through which I rotate from time to time, just to prevent myself from being bored/annoyed by the problems they get stuck in ;)
[marto]: Corion, not bringing the kids would make it ideal :P
[marto]: a suggestion, have one project in the list that isn't programming/perl related
[Corion]: marto: Yeah, things are more parent-friendly the way they are ;))
[marto]: some hardware/makey thing
[Corion]: marto: Ah, I'm currently drifting to that again, over"painting" (well with Inkscape) one of my photographs and thinking about vectorizing some other images ...
[marto]: Corion, yes something 'artistic', so that or some music. Even combine some things, build a musical instrument :)
