Some food for thought :)

Why don't you use Tk::Menu? There is example at widget - Demonstration of Perl/Tk widgets, Menus : 1. Menus and cascades (sub-menus)

Why don't your functions/subroutines take arguments? Why do they work on "global" variables?

Slapping "my $globalvariable" on $globalvariable is not in the spirit of strict, but passing( $variables, $around, is( $in, $thespirit, $of, $strict ) );

 strict itself confers no benefits; The benefits come from avoidance of the bad practices forbidden by  strict :)

Write function, functions that take arguments, functions that return values, functions that don't operate on global variables , but functions that pass variables around
