-% OK : verify a85_getc for really eating EOD (~>) chars
-% OK : find and catalogize `|' and other one-char abbrs
-% OK : shorter operator names (i.e `E' for `def', as in test_vm_eps.eps)
-% OK : shorter var names (such as `preread', `past')
-% Not: make global vars numbered, not named...
-% OK : make constU[]-3 a string, not an array
-% OK : make constW, constP, constL strings, not arrays
-% Imp: inline all except fvMktree (too long), fvFree (recursive) and fvWork (too long)
-% OK : verify, examine StateCatDict (45)
-% OK : find unused vars (such as `moo') in StateCatDict
-% OK : is constM or 1<< faster?? (decided 1<<)
-% OK : anti-`/z 42 eq', ensure `eq' compares numbers (INT_EQ)
-% OK : verify if/ifelse for ENDIF
-% OK : verify direction of `for's
-% OK : eliminate `stopped' context because it catches errors
