them, with signature elements rewritten to quoted versions of the same, so
that we get a better result for the name of the contract used by contract
errors.

retrieved, so having each export be a cons of an accessor/mutator pair is
misleading. Remove the mutator, just have the unit set-box! the box directly,
and just export the accessor.

exactly what unit/c is doing here that's appropriate for fixing this
section of code. ASCII art diagrams for the win!
This also shows how a unit/c contract addition differs from the use
of unit/new-import-export to switch sigs, which means that I'll likely
not be able to unify as much of the guts of the two as I'd like. Schade.

define-unit with the application of a unit contract. So you can think
of it as a define/contract for units that keeps the static info needed
for link inference.

makes sense or not, we'll see. Easy enough to set up, and it also sets
up the plan for a new form I'd like to add, which is why I've factored out
the syntax classes into their own file.

* Fix contracts for signatures and units so that references to
other signature members work appropriately.
* Add text about signature and unit contracts to the Guide.
