Hello!

   I am trying to understand how the module system used by SISC
interacts with the low-level macros that SISC supports.

  Specifically, I am trying to figure out why the follow snippet of
  code, an anonymous module that exports amacro and thefunc,
  doesn't work.

   (module (amacro thefunc)
     (define-macro amacro (lambda () (thefunc)))
     (define (thefunc) (display "\n\n===\n\n")))

  After I pasted it in the REPL, when I call (amacro) I get:

   #;> (amacro)
   Error: undefined variable 'thefunc'.
   console:16:7: <indeterminate call>

  Curiously, if I just go ahead and type (thefunc) it works:

   #;> (thefunc)


   ===

   #;>

   Is anyone able to explain to me why this happens?

Regards,
 Igor.
