Quite right.  And I recall being confounded by the function pointer 
syntax; it never fit in my mental model of how the rest of C worked.

Anyway I was not intending to defend C choices,  merely to point out 
an advantage this choice gave me.  On a language without garbage 
collection,  the indirection was very important to keep in mind.
