[MacRuby-devel] C-level blocks (issue #712)?

[Caio Chassot]

So It seems to me the only change there is uninlining the lambda and assigning it to a throwaway variable. That feels like busywork.

I suspect this has to do with keeping a reference so it doesn't get GC'd. Just a hunch. Am I getting there?

Why is this needed?
