---% Interpreter Code Generation Routines

---Modified by JHD 9/9/93 to fix a problem with coerces inside
---interpreter functions being used as mappings. They were being
---handled with $useCoerceOrCroak being NIL, and therefore internal
---coercions were not correctly handled. Fix: remove dependence
---on $useCoerceOrCroak, and test explicitly for Mapping types.
