Now the comment needs updating as "just put in common" also applies to
the "new" case. Or you can also remove it ("just put in common" is
somewhat redundant with the other comment anyway).

"needs" should be aligned with "If" like it was before; same for "for".

Now we are in pretty good shape.

The ICE happens with invalid code after reporting an error, correct?
Then I agree, this should rather wait for stage 1.
