context transfer on th
on't like the literal $ME. It usurps a variable name that
has been legal for customer use in prior Perls. Why not use something
more "system-belonging" like %_ or even $_? In fact, "self" in $_ and
"args" in @_ has a nice symmetry. Or we make $_->{self} be
have a separate "method" type.
Oooh. Getting better all the time! Or maybe just return undef, and
let the method call fail on the undef, or we could check it ahead:
if (my $me = self) {
$me->do_this
} else {
$CGI::Q->do_this
}
To steal
$a == "" $b)
so that it's DEFINITELY a string comparison.
No, let's not set Perl back 13 years, thank you very much.

Already done in 5.6. :) "perldoc perlre".

Heh! All that typing I would have saved over the years, would
probably be equal to the number of characters I've typed here
debating this point. :)

reaction to this proposal. "If you like Python,
you know where to find it, but let us have some primitive data types
in Perl that act primitive so we can optimize things."
Here's hoping I don't have to prove that, and Larry will just reject
this proposal outright. :)

Heh ... flashback to the V7 Bourne shell (the One True Shell) source
code, written in Algol, #define'd so that it would compile with C. :)
Truly a masterpiece of well-intended-but-poorly-executed famous last words. :)

k about which single element to pull
out.
Since there's no general rule for converting a scalar to a list
(there's only twenty or so specific rules :), there's no consistent
way to take this coerced "list in a scalar context" and wrangle it
back to a scalar!
