From @usev6

There is no longer a Null PMC access error when hitting 'last' in code block in regex in loop​:

$ perl6-m -e 'repeat while False { "foo" ~~ / "f" { say "got here" } "o" { last } / }; say "after the loop"'
got here
after the loop

$ perl6-p -e 'repeat while False { "foo" ~~ / "f" { say "got here" } "o" { last } / }; say "after the loop"'
got here
after the loop

$ perl6-j -e 'repeat while False { "foo" ~~ / "f" { say "got here" } "o" { last } / }; say "after the loop"'
got here
after the loop

I added a test to S04-statements/last.t with the following commit​: Raku/roast@95bf03a714

The RT System itself - Status changed from 'new' to 'open'

@usev6 - Status changed from 'open' to 'resolved'
