in thread Global vs. local?

While the name is weird, if you're using a variable to hold it, you can perfectly call the subroutine through that name. And using weird names is good for named subroutines that get autogenerated by code:

my $subname = '1Button_Click';

*{$subname} = sub { print "Hello World\n"; };

no strict 'refs';
$subname->();

The question is wether it is good to name subroutines autogenerated by code in the symbol table. With a dispatch table hash you can name your subroutines by chunks of jpeg files, nice. But symbol tables are namespaces and their entries good for importing/exporting/localizing. I'd rather expect programmers to adhere to perl principles here.

Q: Why do you do that?
A: Because I can!
