Agree. Imagine we have 3 generic libs/modules...
"Optimized CTFE Polygon Primitive Lib", Math, Gfx
... and then the "end user", creates a program.

Both Math and Gfx, want to use the optimized Polygon in their 
modules...

[Polygon(...)]
struct SpaceShip
{
}

This is just as ambiguous as if you had used a built-in int:s... 
and it can be solved in the exact same way which I outlined in 
the other thread.
