> I've seen a few people on the mailing list asking for something like this and
> I've wanted it myself, so I went ahead and implemented a parser for a
> lisp-like way of generating Expressions. Calls are of the form {{{}(<fn>
> <args>){}}}, scalars are of the form {{{}$type:value{}}}, and field refs are
> of the form {{{}!<dot path>{}}}.
