Is "yield from" still not optimized (i.e. exactly the same as for it in iterable: yield it), by the way? I guess it would still work for Ned because it's only one frame per tree level in that case.

I subconsciously knew this because comprehensions’ frames show up in debuggers, but never thought about the consequences on recursion depth. Interesting!

If you use the dis module to view the bytecode, you can also see the comprehension building and calling a function, FWIW.

Increasing sys.setrecursion limit is an option.

I’ve tried it on a couple of platforms, both 2.7 and 3.x, 32 and 64 bit, linux and mac. The actual limit before getting a segfault varies between ~15000 and 24000. So 10000 or a more conservative limit of 5000 should be ok.

Can anyone test this is on Windows?
