Consider this code: 
sub show1 { ... }
sub show2 { ... }

my $a = 'foo';
show1($a);
show2('$a');

How can I write either show1() or show2() so that STDOUT displays this: 
$a = 'foo'

[download]
This is trivial in C/C++ using macros, but I can't figure out how to write either show1() or show2() so that it knows the name and value of the variable passed to it from a different scope.
