in reply to Re: Re (tilly) 1: grep instead of foreach?
in thread grep instead of foreach?

is using a hash-slice there. The idea is: to address more then one entry in the hash at once. a simple example:
my %languages; $languages{'python'} = 'boring'; @languages{'perl', 'perl6'} = ('cool', 'real soon now'); # this is short for ( $languages{'perl'} , $languages{'perl6'} ) = ('cool', 'real soon now'); # or $languages{'perl'} = 'cool'; $languages{'perl6'} = 'real soon now';

There are also array-slices.

Read perlman:perldata

[GotToBTru]: late to the conversation .. but thanks, Corion, for the reminder about Perl::Tidy
[Corion]: GotToBTru: Heh ;) I'm not really endorsing it, as I found that any gains made through it are easily squandered by the hours spent on configuring it. At least in my case :)
[GotToBTru]: Like most Swiss Army Knives, you can cut yourself trying to find the blade you actually want
[GotToBTru]: i am satisfied with the default settings turning the seemingly random formatting into something reliable
[Corion]: GotToBTru: Yeah, I started a quick(ly implemented but slowly running) implementation of a program that would guess the "best" configuration (that is, least amount of changes) from my code, but then found that it stops parsing the source as soon as it ..
[GotToBTru]: sadly, it can't do anything about this
[Corion]: ... encounters sub foo($bar,$baz) {, which is something I like nowadays
[Corion]: GotToBTru: Yeah, that stuff is hard to do away automatically ;)
