If bareword filehandles no longer exist in Perl 7, how do you refer to STDOUT, or more commonly, STDERR, as in print STDERR "oops: ..."? Or, for that matter, STDIN, as in <STDIN>?

Is autoquoting here the token to the left of fat comma or is this the long-deprecated general bareword misfeature that use strict; has long disallowed?

And what is the supposed justification for removing heredocs?

Why is this starting to look like Perl6 all over again, just with a less-ambitious goal? Perl6/Raku at least had the excuse of targeting ahead-of-time compilation to machine code. What is the supposed benefit to Perl7?
