The contracts I wrote in the patch do reflect this via the
`stx-pair?` predicate, FYI.
By the way, the definition of a syntax pair in the documentation is
this:
A synta

Is that really so misleading though? There is already precedent for
functions which take arguments not exactly matching their

Given the name, I would have thought they only worked on syntax

Hi all,
Recently I was using the `stx-car` function from `syntax/stx`. At some
point, I had called it on a non-syntax pair and the error message came

Can we get syntax-first and syntax-rest while you're at it? (I looked for these
just a couple of days ago, and like Vincent, I got the stx- wrong)

Just realized after I sent it that I'd change two things in the patch:
* `syntax-null?`, `syntax-pair?`, `syntax-list?` would be defined

Hi all,
Recently I was using the `stx-car` function from `syntax/stx`. At some
point, I had called it on a non-syntax pair and the error message came
from `car`, which is used inside the implementation of `stx-car`.
I thought it would be nice to add contracts in `syntax/stx` for better
error mess
