(And this is what Matthew's last example gets by changing `f' to a
macro, right? Also, Stefan posted a related message to the
scheme-reports list where he imlpemented some new #. thing which is
(roughly speaking) something that expands to a `let-syntax' and
therefore tries to do the same.)
In any case, it would be nice if the original example I posted (which
is a variant of what was discussed originally) would throw an error
instead of looking right in a way that is wrong...

evaluates to 1, but if I change the first two "stx" names into "x"
*or* if I change the argument name for the macro to "x", then it
returns 2.

When I thought about this, I was pleasantly surprised that
`syntax-parameter-value' could be used in exactly the same way.

FWIW, that's true -- and a reason that I plan to change what xrepl
(our command-line thing which I added to Racket recently) so that it
intercepts any line that starts with a "," which means that it would
work no matter what the actual language read

A possibly useful analogy is with `fluid-let' which doesn't create new
bindings, but rather `set!'s them. But IMO `fluid-let' should die, so
using parameters is a better example...

l substrings.
One last not-too-related note: this is IMO all a by-product of a bad
choice of common regexp practices where capturing groups always refer
to the last match only. In a world that would have made a better
choice, I'd expect:
> (regexp-match #rx"(foo+)+ bar&q
with just
a single argument, then that last optional flag is t -- which is an
unconventional thing for elisp functions...
(BTW, I'm subscribed to the list now, so this should go through.)

different direction. (And we did not follow perl in all aspects, as
those tests clarify.)

example, some macro that wants to generate a path), we'll
use strings or byte strings, with the latter more common for lower
level things.
(But I'm just rambling now, I haven't slept in N days -- so feel free
