I think that the specially named subs deserve having beautiful names. OTOH I don't consider __DATA__
to be "ugly names" at all. They're nice as special tokens, and I must say I regret they (being supposed) not to be there in Perl6.
As Larry himself wrote once, the shebang line
is much like a "hello!" and the
line is much like a "goodbye". Now IIRC it is supposed to be taken away in favour of a pod (or whatever it will eventaully be called) directive. But I mean: maybe it's just me, but I'm really keen on that "__END__".
