but should it
be set fron the command substitution for the assignment to c?
I think it'd be practical, is there a reason why it shouldn't?

It's unspecified. The assignments are performed `beginning to end', but
it's not specified when $? is set. Interestingly, the SVR4 sh and ksh88
both set $? as each command substitution finishes, but POSIX didn't specify
that behavior explicitly. Maybe the 1992 authors didn't feel they had to.
And while
we're at it, is there a reason why assignments in a simple command
shouldn't be applied sequentially, from left to right?
The Bourne shell performed the assignments right to left. This came up on
the austin-group list a couple of years ago, in almost exactly the same
way, but I don't think the discussion made its way to an interpretation
request.
