P.S.:  Hats off to whoever adapted m3tk for LONGINT.  There are places _everywhere_ that needed
modification.  The whole thing is about as pedantic as code gets.  Layers upon layers of
linguistic abstractions that do mostly zero semantic abstraction.  I traced two declarations
through 10 levels each of referrals to other interfaces, all but one of them just renames
with the same simple name and different qualifying interfaces, before finally getting to
something with some meat.

The whole thing smells very strongly of the Ada/Diana culture of ASTs.
