The trouble is that this conflicts with another ancient and venerable
principle of programming:  declaration before use.

The cleanest answer would seem to be to have a set of programming tools
which let you construct a forest of entities (types, variables, functions)
and generate vanilla C code on request.  (Sort of an |R**n for C.)
(Preprocessors don't *have* to generate unreadable code; some of the
clearest Fortran I've ever seen came out of a preprocessor.)
