I think you mean that if you have
module M(f) where
f = ...
g = ...
precompiled in a library, is it possible to call g?
No, I'm afraid it isn't, at least in GHC. For example, 'g' may no longer
exist... it may have been inlined into 'f'.
At least it is possible to access 'g' from GHCi if the module is loaded
in interpreted mode.
