Alternatively, return a reference:

sub givelist {
  [ 1 .. 10 ]
}
say givelist()->[ 2 ];

Update: In fact, if the sub is declared before it's called (as above), the call can be simplified to:

say givelist->[ 2 ];

You don't really need to change the function to use a reference based solution. `use Modern::Perl; sub givelist { return 'a' .. 'c'; } say [givelist()]->[1];` [download] Ron	[reply] [d/l]
