[perl #77754] [BUG] Null PMC access when calling .perl on callframe.my in Rakudo

[Christian Bartolomaeus via RT]

This fails now with X::NYI and an adequate error message:

$ perl6 -e 'say callframe().callframe(1).my.perl'
Callframe.callframe not yet implemented. Sorry. 
  in block <unit> at -e:1
  in any <unit-outer> at -e:1

I wonder whether this ticket could be closed now or how a proper test would 
look like.
