Oh yes, of course. 'low-level' is a relative concept though. Do you 
think CFFI's current approach is too high-level?

1. foreign-symbol-ptr to get a pointer to the foreign variable.

2. defcvar to define a symbol macro for accessing a foreign variable 
(built on top of foreign-symbol-ptr).

3. eventually expand defcvar to do more for the user wrt to memory 
management.
