The patch seems to me to be OK as far as it goes.  I brought up the
other points only because I wanted to be sure that it wouldn't be
inconsistent with the next step; but it seems we're pretty well agreed
that we aren't going to do anything that would break this.  So I have no
problem with applying as-is, rather than waiting for an all-inclusive
patch.

But you had mentioned wanting to look at reducing overhead by using
exec_eval_expr(); were you intending to do that before committing?

As far as the subsequent discussion itself goes, Pavel and I seem to
be pretty unsuccessful at convincing each other of our respective
visions of what an exception ought to be.  Any opinions?  Should
we be taking this thread to -hackers for a wider audience?
