Hmm.. I can't believe I missed that. While that exact macro wouldn't
apply in my situation (because I fetch the value from a field in a tuple and
not the argument of a function), the underlying concept is the same as
what I would need. Now I do not need to feel the wrath of unnecessary
memory allocation/deallocation for the non-toasted case. Excellent.
Thanks very much!
