These are $HL features. I can imagine that Perl6 will stuff the C<caller>, the subroutine's name and more into P0's properties, if e.g. debugging is on, or these items are referenced.
Exactly. If a language want to expose any sort of introspective information, it should do so.
Having said that, a standard mechanism to do so--perhaps a sub pushing the passed-in continuation onto the control stack as a special type of entry, or pushing its name on the stack (or both) wouldn't be out of order so those languages that want to do this can do so in a standard way.
