is $chunk_of_code supposed to contain Perl code? If so why? When would
you use this? What does this assign to the variable? I am assuming a
true false value but I am not sure.
print $chunk_of_code;
to that little program, it prints:
if ($condition) {
print "Gotcha!";
}
So it would seem to be a useful way of putting code into a variable to be printed later without having to escape all the special characters. It may have other uses. I'm going to remember this one, it may come in handy! ^_^
