Comment(by simonmar):
Replying to [comment:2 simonmar]:
> We established (during a conversation on IRC) that the reason for the
lack of unboxing was that the function wasn't inlined until after the
worker-wrapper transformation. The question is therefore, why wasn't it
inlined earlier?
I think I must have misunderstood the IRC conversation in question, tibbe
told me today that the function does indeed get inlined before strictness
analysis and worker-wrapper. tibbe: if you could attach the output from
`-dverbose-core2core` to the ticket, that might help.
