This functionality does not need to be built in to STk, it could be
provided by a separate tool you just run (ala C lint) to check the
code. I believe there exists several possibilities. One is to use one
of the existing scheme compilers such as `hobbit' or `stalin' to check
the code.

You may also want to check out Andrew K. Wright's thesis "Practical
Soft Typing". I still have to get round to reading it, but he
describes ways to lay down a type-discipline on top of standard
scheme. This is probably beyond your immediate requirements, but there
is also a tool to go along with the thesis. And since he graduated
from Rice, it may even be somewhat integrated with the DrScheme
mentioned by Lars Thomas Hansen.
