You're talking about a deprecation cycle. Either you intend the remove
the current location, or you don't. And in the latter case, the warning
is pointless (and there's no deprecation).

Look, if one thinks it's a huge improvement to no longer type "perl" in
front of syntax, wouldn't it be much better to educate perldoc? If $ARGV [0]
cannot be found, and $ARGV [0] !~ /^perl/, try again with "perl" . $ARGV [0].
Or use a table that maps $ARGV [0] to a canonical name.

That can be part of 5.14, noone has to learn a new names, old references
continue to work, and one doesn't have to wear out the p, e, r, and l

Abigail (or course "man perlsyn" is still shorter than "perldoc syntax").
