Hello,

And what happened to tree/block statement iterators?  You said you

like them,


I don't like the purpose for that block statement iterators were
created
and their internals; otherwise I like the idea.

Have you actually tested the insert (both edge and non) iterators, for
instance?

yes, to some amount (they are also used in ordinary un-ssa).

But un-ssa has actually not, to my knowledge, every exposed a bug in the iterators, while PRE has done it frequently.

Given that
now they are trivial, I don't fear there would be any major problems
with them.

I'd be happy to test them if you sent me the huge patch.
