[racket] Search & wrap

You say "wrap" but in your example you replace the call of function b with
another function.

Without a specific use-case I'm not sure about the use of speculating on
your meaning.

Would you be satisfied with
(search&wrap function-b
   (define (function-a ...) ...))
or
(define (function-a ...)
   (with-function-wrapper ([function-b ...]) ...))
?

Otherwise it seems like you are asking for something that precludes
separate compilation and has effects that cross module boundaries... sounds
unpleasant if not terrible.
