Ohsure, that could work. But for that matter the following already
works right now on all versions of perl
sub foo { ... }
BEGIN { Sub::Util::set_prototype( "$", \&foo ); }
But is that really what we want to encourage new authors of perl code
to be writing?
If we preferred that form, why would we have designed the `:prototype`
attribute in the first place? My aim was to allow people to continue
writing what is valid and encouraged in both *current* perl 5.32 and
proposed perl 7.
