Greetings monks, new Perl hacker here, about three weeks into the journey, having fun and figuring out the lay of the land.

Alright, so perldoc -f say tells me this:

This keyword is available only when the "say" feature is enabled; see feature. Alternately, include a "use v5.10" or later to the current scope.

This leads me to believe the following code shouldn't work.

use strict;
use warnings;

say STDOUT 'like a charm';
[download]

Yet with an explicit filehandle, it does work (tested on v5.16 and v5.14). The question in this case is: why does the code work?
