As you've pointed out, the comma is the list operator.

What do you mean by that? Commas can construct lists, but only in list context. Commas in scalar context don't. Witness:

#!/usr/bin/perl use strict; use warnings; sub context { print wantarray ? "LIST\n" : "SCALAR\n" } my @a = (context, context); my $a = (context, context); __END__ LIST LIST SCALAR SCALAR
