module trickery

[Thomas Bushnell, BSG]

I need to evaluate expressions in a defined module.  I do this with:

(eval-in-module EXPR special-module)

special-module is very carefully constructed.  It gets variable
definitions from certain other places, all of which work just fine.  I
also need it to inherit syntax definitions from a specified module.  I
use the following to grab the relevant syntax:

(module-use! special-module (resolve-module '(python syntax)))

The (python syntax) module creates syntax with define-syntax, and does
nothing out of the ordinary.

When I evaluate expressions in special-module which use the syntax
defined in (python syntax), things go into an infinite loop.  The
macro I'm testing is blindingly simple and works fine in a normal
environment.

I am not wedded to this particular arrangement: anything that imports
the macros from one module to another works, provided I get to use
define-syntax.

What might I be doing wrong?
