in reply to descending a tree of hash references

I've been in your exact same position before. Here's a snippet which may save you some hair-pulling:

#!/usr/bin/perl -w use strict; use Data::Dumper; my $s = { foo =>'bar', baz => { troz => 'zort', blort => { poit => 'qux', } } }; print Dumper $s; # This works in 5.6.1 and later set($s, qw/baz blort poit/) = "Whee!"; set($s, qw/baz troz/) = "Joy!"; # In 5.6.0 (and earlier) you have to: # set($s, qw/baz blort/)->{poit} = "Whee!"; # set($s, qw/baz/)->{troz} = "Joy!"; print Dumper $s; sub set : lvalue { @_ == 1 ? $_[0] : set($_[0]{$_[1]},@_[2..$#_]); }

perl -pe '"I lo*`+$^X$\"$]!$/"=~m%(.*)%s;$_=$1;y^`+*^e v^#$&V"+@( NO CARRIER'

[Discipulus]: Tanktalus we will be glad to have you here more frequently, tho ;=)
[marioroy]: Lady_Aleena oh I thought you found the error by adding -exec mp3info
[Tanktalus]: Discipulus: I should be working on an interview test right now. Well, I kind of am, but keep getting myself distracted :)
[Lady_Aleena]: marioroy, nope, that IS the error.
[Discipulus]: oh to be distracted PM is still a wonderfull place
[Tanktalus]: Problem is, it's a test for another monk - as in, another monk letting me interview for his company :)
[Tanktalus]: He might see me here... :D
[Discipulus]: it's me? ;=)
[marioroy]: Lady_Aleena could it be a quoting issue? I just tried find with -exec on the command line. find . -name "*.pl" -exec ls -l {} \;
[Tanktalus]: No, I know who he is, nice try. But if you're hiring, let me know :)
