I just noticed that this is a change you made in
the last revision, and that consistency also implies
that syntax-case is wrong.  I've always felt slightly
nauseous when I thought about syntax-case, and now
I know a good reason for it.  I suppose the syntax-case
users are not eager to remove the parentheses around
their <formals>?  Please?  Oh well.
