C does not have functions as first class data, you can only use functions
pointers as data.  To see the difference just try to write a function
that does function composition.  For simplicity assume that all functions
take and return int, i.e. write an
	int (*compose(f, g))()
	int (*f)();
	int (*g)();
(ANSI-fy if you like)
so that (*compose(f,g))(x) == f(g(x)).

I claim that this is impossible to do in a portable way.
