Only as a Sunday morning thoughts from me:
Ideally, a library knows best how to handle a complex expression of
their own objects.
So, one have to bring the complete expression into the library, but how?
Suppose a C + + math library-"MyDream" know themselves how a complex
compound expressions such as "A = (B * C + D) * E" is to handle
Could Lua call my mydream library with the AST of "A=(B * C + D) * E"
instead of evaluating it itself somehow?
Mmh... sound a like a job for metalua...
