Sounds like this needs a bit of re-thinking.
Given a set of function signatures:
The user calls:
F(A,B,C) (no relation between a,A ,etc)
How do we find the 'best' match?
I think we can start with:
1) Only allowed (at most) 1 conversion on each argument
But what is the 'best' match mean?
I think that can't be decided without some sort of hierarchical relation of
Now given a hierarchy, I still don't know the solution, but it sounds like
some kind of graph algorithm.
