They are not controversial with *me*, and the complaints about either
that were repeated today don't impress me much.  The only concerns I
have are:

- Should we allow [x, y for x in s1 for y in s2] or should we require
that to be written as [(x, y) for x in s1 for y in s2]?

- What does a += b += c mean?

Plus doubts about the cleanliness of the implementations given by the
currently proposed patches, e.g. Thomas' doubt about the use of so
many new opcodes (which I think is actually fine).

Agreed.  Besides, our priorities should be focused on the 1.6 release
