+**** Intra compilation unit call optimization
+
+We could have a mechanism similar to what we use for optimizing calls
+to primitive functions.  IE using a link table for each compilation
+unit (CU) such that calls from functions in a CU targeting functions
+in the same CU don't have to go through funcall.  If one of these
+functions is redefined a trampoline is compiled and installed to
+restore the redirection through funcall.
