Here's some code: 
#!/usr/bin/perl -w
use strict;
sub FOO {
    return qw($bar $foobar);
}
my $foo = '$bar';
print "It matched!\n" if (grep /$foo/, FOO());

This fails, even though it should work. And this code works if i change this line: 
my $foo = '\$bar';

[download]
Which looks (to me) like /$foo/ is interpolating $foo twice. Why is this?
