On our dev IRC channel ( https://webchat.freenode.net/?channels=#perl6-dev ) we have a bisectable bot ( https://github.com/perl6/whateverable/wiki/Bisectable ) that can take a chunk of code and tell you when its output changed. perl6-debug-m currently dies with this error. Hunting what's causing it is a good start: ``` Non ast passed to WANTED: NQPMu ===SORRY!=== Cannot find method 'named' on object of type NQPMu ``` > More difficult questions, but you may know answer. > > 3) Why is it not possible to arrange for a break inside a module?
