Yes, this is was my plan for implementation of multiple functions.  I have
never written the full DOCS, sorry.  The return item doesn't have to be 
a function, it can be a data structure (for a driver header, for example,
or a vector of function entry points).

I did test many of these things in developing DXEs.  The real problem with
DXEs is they can't call some libc functions (like I/O).
