> But why cant we modify a static string, sure it is "static" but if during execution perl creates a (non existant) variable to store it in.

You could try something like:

use strict;
my $foo = "bar";
my $test = sub { my $string = "$foo out"; $string =~ s/b/f/; return $s
+tring };
print &$test,"\n";

It's not really what you were asking for, but it lets you modify a string, and still have it seem static afterwards.
