Hang on... \I \E amounts to the same number of characters as using
'. .' (that is, terminating this q-string, concat the thing, start

For arrays, yes, the proposed \I \E would still be useful. Maybe the

You can't do that in a 'HERE' doc.
True.

But it makes "short-circuit as soon as Cgrep

I would propose that the Cgrep operation should short-circuit if the
block throws an exception, with the value of the expection determining
whether the final invocation of the block should accept the element it
was filtering:
Otherwise nice but until now die() has been a serious thing, now
Exactly the sort of chicanery grep/last is meant to avoid. So the question
becomes, how do we crowbar "last" in without altering the returned value in
Cmap blocks. I'm for putting it after a comma. Which matches the syntax of
John Porter's proposal about internally converting the block to a

grep doesn't short-circuit.
I never did figure out why "last" {w,sh,c}ouldn't be made to do
that very thing.
Agreed, that would be very natural.
