I'm confused.

tachyon posted an interesting solution, but i can't makes any sense of it.

first of all, i could find no mention of /c in perlman:perlre, but perl didn't barf on it -- so what does it do?

second, i tried the following near-identical code and it didn't do at all what i expected: 
#!/usr/bin/perl -w
use strict;

my $string = "foo bar baz bar quux foo gin";
my @list = qw(foo bar);

$string =~ m/\Q$_\E/gc for @list;

my ($rest) = $string =~ m/\G(.*)$/;

print "$rest\n";

[download]
.. it printed: 
foo bar baz bar quux foo gin

[download]
and honestly, i can't see how it could possibly work the way you wanted it to. it seems to me that the /g on the m// would cause the 'foo' to match at the first and sixth words, and then the 'bar' to match at words 2 and 4, leaving the \G assertion after word 4, not after word 2 where i think it belongs.

obviously, i'm missing some of what's going on here. can you enlighten me?
