Now I would like to be able to enumerate precompiled public functions in modules that I might use as building blocks in such dynamic compilation. So far I'm not seeing anything that does this directly. Can anyone provide some pointers?
If it's just not possible to introspect on compiled modules, then I suppose I could use external metadata of my own, or even perhaps haddock info if it exists, to attempt to generate this info. Clearly though,

I have no idea how it works, but I'm pretty sure yi does this --- e.g. if you hit M-x (when in emacs emulation mode) and then tab-complete, you see a list of all the available functions. Maybe you want to take a look at the yi source code and see how they do it.
