Using '__SUB__' made me think it was a compile-time constant such as
__FILE__ and __LINE__. It isn't, so I think it's not very good naming.
Why not make it look like a regular function or keyword, such as
sub {
print "$_[0]\n";
caller_cv(0)->($_[0] + 1) if $_[0] < $arg;
}
In fact this is already available on CPAN as Devel::Caller. Is this
something common and useful enough to make it part of the core language?
I'm not really convinced of that.
