Only for really used combinations (i am using "duck typing" inside 
templates).

In any case, unused functions in the resulting file is not included.

This problem would help solve the availability of inheritance for 
structs or compile-time creation of class instances.

But now the compiler can identify duplicate parts of the code, working 
with the same types
