in reply to Returning and using a glob from a sub.

This covers most of what you might want of put into a glob (though there are a few other obscure possibilities: io handles and formats): 

Perl> *it = \'"1..4"';;
Perl> *it = [ 1 .. 4 ];;
Perl> *it = { 1 .. 4 };;
Perl> *it = sub{ say '?1..4?'; };;

Perl> sub getIt{ return *it };;

Perl> $g = getIt();;

Perl> say ${ $g };;
"1..4"

Perl> say @{ $g };;
1 2 3 4

Perl> say %{ $g };;
1 2 3 4

Perl> &{ $g };;
?1..4?
