in reply to Why do I need 'use 5.010;' ahen I am running '5.24'

say states:

"say is available only if the say feature is enabled or if it is prefixed with CORE:: . The say feature is enabled automatically with a use v5.10 (or higher) declaration in the current scope."

See also feature.

#!/usr/bin/perl

use feature say;
say 'derp';

Update: doh, the above will fail with use strict; so:

use strict;
use warnings;

use feature 'say';

say 'Derp';

    That is why I use 5.12, as that implies strict:

    $ perl -we'use 5.10.0; say 1, $x'
Name "main::x" used only once: possible typo at -e line 1.
Use of uninitialized value $x in say at -e line 1.
1
$ perl -we'use 5.12.0; say 1, $x'
Global symbol "$x" requires explicit package name (did you forget to d
+eclare "my $x"?) at -e line 1.
Execution of -e aborted due to compilation errors.
