Nice to see that the developers of Perl are still solving the important problems:
say() is a new built-in, only available when
use feature 'say'is in effect, that is similar to print(), but that implicitly appends a newline to the printed string.
A new prototype character has been added.
_is equivalent to
$but defaults to
$_if the corresponding argument isn’t supplied.
This is exactly the kind of stuff that made me give up on Perl. And mro is a pretty horrible new feature too.
