The qq function does interpolation so ${ is seen as dereferencing something that isn't defined.

You didn't mention the other warning "Subroutine menu redefined at call_b.pl line 9." I don't know anything about CGI or URI so not sure if that is an issue. But it looks like calling uri_escape is returning undef.

Something else I noticed is that my $go_menu = &menu; will not assign anything to $go_menu since menu doesn't return anything.
