in reply to [Solved] Pick a single item from a sub's return list

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];
