Yeah, I figured out that that would work (although I had forgotten
about define-syntaxes-- shouldn't that be define-syntaces? no, I guess
that rule is only for -ex).  But I defined the syntax helper function
at the top level so I could test it interactively, by building up
syntax objects and then running them through the helper function to
make sure it was doing the right thing.  Sure, once I got it working I
should have moved it into the body of the define-syntax, but I found
it surprising that it made a difference.
