42 chars in the sub.

use strict; my $s = "abcdefghijklmnopqrstuvwxyz"; my $t = "for"; print x($s,$t),"\n"; $t="perl"; print x($s,$t),"\n"; sub x{ my($s,$t)=@_; eval"\$s=~tr/$t//cd"; $s eq$t; }
one less:
sub x{ eval"\$_[0]=~tr/$_[1]//cd";$_[0]eq$_[1]; }

    Interesting method, but it doesn't properly handle:
    my $s = "abcfoforrxyz"; my $t = "for";
    There are also serious escaping issues with the interpolated code inside the eval :)
