This is ready.

I'm a little surprised to see that this is only on the M2M. I figure the M2L would need this most. Did you investigate whether it makes a difference there, too?

(Also, thank you for working on this!)

I couldn't figure out how to do the same thing in M2L and that's why I submitted !64 (closed)

Fair point--I don't see an obvious way either.

L2L is also tricky.

Looks good. Thanks for working on this!
