If we do this, we also need to consider whether we want to make the corresponding change to regular for-loops. Seems to me that all the reasons it's a good idea for listcomps apply to for-loops as well.

I expect there's no chance: unlike listcomps, for-loops allow break statements, and search loops that use the for index after a break (and out of the loop!) are common.

Another advantage of changing both together is that we can continue to describe listcomp semantics in terms of for-loops

But I'm afraid that's also an advantage of leaving both alone.

instead of lambdas.

Then we won't have to go into hiding until Guido dies or lifts the fatwah against us.
