Huh? I don't see it this way. There is *no* sharing between the frame
of the generator and the frame of the block. The block is a permanent
part of the frame surrounding the with-statement, so all names are
shared there.

No, I was just proposing putting 'collapse foo' in the module, which
would mean that (a) the definition of foo is intended to be a macro,
and (b) all uses of foo are intended to call that macro.

But I still think this whole proposal is built on quicksand, so don't
take that suggestion too seriously.
