The underlying error is​:

Method 'is_dispatcher' not found for invocant of class 'Block'

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

From @donaldh

Oops, I meant to say​:

The underlying error is​:

Method 'is_dispatcher' not found for invocant of class 'Block', happening inside a try block in Per6​::Optimizer optimize_call($op) line #​1273

This looks a lot like the UnwindException exception problem I'm already working on, but the same fix does not seem to apply. I will investigate further.

From @usev6

This works now as expected​:

$ perl6-j -e 'for 1 { last; ENTER { say "hurz" } }'
hurz

I added a test to S04-phasers/in-loop.t (and unfudged the skipped tests there) with commit Raku/roast@da7ff73062

I'm closing this ticket as 'resolved'.

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