Well I'm sincerely certain that they are.
my &say := &print.assuming(:ors("\n"));

Ugh. You do!? I think that's the biggest PITA in Perl. I never
thought of "say", but I've been known to write:
sub p { print @_, "\n" }
In some of my more verbose scripts.
It's a sign that something's wrong when on every one-liner I write, and
in even some longer scripts, I specify -l on the command line. C<say>
is indeed shorter than C<print>, and I like that, because I use it more
often.
Will there also be:
sub complain([EMAIL PROTECTED]) {
print $ERR: @_, "\n";
}
:-)

Uh huh, but the ones I have experience with use it as a method, so it
doesn't interfere.
$bot.say("Welcome, $user")
Plus, a lot of people use C<index> to create an index, C<length> to find
the length of an array, C<delete> to delete files, C<study> to do their
homework, and C<die> to commit suicide (or was that C<goto>?). That's
why variables have sigils, and lexicals have scopes...
You even said yourself:
my &say := ...
That works even if C<say> is built-in.

Doesn't matter, because most of these decisions are up for discussion.
I think everything that was "decided" when Apocalypse 3 was written has
changed at least three times (contrast with Synposis 3 :-).
