Very cool!
I suspect there will be *lots* of changes in the RTS to make this go.
We might want to see if we can use an abstract type for "possibly tagged
closure pointers" in C to make things clearer / less fragile and to help
flag code that might need to be changed.
I'd like to test this stuff independently of spec-eval - I have a
feeling it might be an improvement on its own. Any chance of getting a
patch for the HEAD?
Cheers,
Simon
