    - need to change current*port functions to actually have a current port, and other i/o operations to use the correct current port
      issue here is, to do this right we need parameterize and dynamic-wind. both of which would be nice, but are a lot more work, too
+     * best place to start may be call-with-values, as that is needed before dynamic-wind. 
    - vectors - limited use in cgen module - make-vector, vector-set!, vector-ref, list->vector, vector->list
      obvious issues are how to represent the vector (array of objects, I suppose) and how to GC it, including handling mutations
    - what else? there must be more stuff
