Yes, my mistake.  But that doesn't change the thrust of my last post.

I'm not sure whether or not it's worth constructing these  temporary
macros defmacro and defun - We've only got 2 defmacros and 4 defuns for
them to process, after all.

But I'm glad you seem to agree with the idea as a way of getting rid of
the extensive hand expanded backquote forms in byte-run.el.

By the way, I'm still working on the feature/positioned-lambda branch
after finding a bug there.  I'll get around to answering your reply to
my earlier post soon, hopefully.
