Ah, so this is a terminology issue. I'd say that a and b are *called* in  
function c, not *bound*. I've never seen "bind" used in this sense before,  
but as Humpty Dumpty said to Alice:

- When I use a word, it means just what I choose it to mean -- neither  
more nor less.
- The question is, whether you can make words mean so many different  
things.
- The question is, which is to be master -- that's all.

(Lewis Carroll, Through the Looking Glass, ch. VI)
