 * currently remaining rtyper topics: 
 
-  - (hard) (holger, armin) prebuilt constants -- PBCs -- and dicts with PBC keys
-    DONE 1. call to memoized functions, at first with a single PBC arg 
-    DONE 2. removed the only usage of specialize:memo with more than one PBC key

-  - (probably trivial) verify that we've done all the builtins we
