I prefer to use CREATE-.  That way, I can even have a MAKE- and
CREATE- for the same structure, where the CREATE- enforces certain
invariants, fills in optional arguments, tracks the creation, etc.,
before passing the arguments on to MAKE-.  So for me, MAKE- is always
"raw", while CREATE- implies a layer of interpolation (checking,
augmenting, recording, etc).
