Re^5: Stop Using Perl

FWIW:

a new feature allowing to change => from "fat comma" to a kind of "pair operator" wouldn't effect Moose's has() w/o parens.

  DB<105> sub has { \@_}

  DB<106> has pizza => scalar 
                   is     => scalar 'ro'
 => ["pizza", "is", "ro"]
[download]

It's scalar(CODE) which enforces a scalar comma within CODE to only return the last element.

  DB<107> has pizza => scalar (
                   is     => scalar 'ro',
           );
 => ["pizza", "ro"]
[download]

OTOH a changed => doesn't necessarily need to act like a scalar comma.

In other words, fat comma and regular comma would behave differently with regard to parens. No thanks.	[reply]
