they definitely affect compile times.
Does c++ not “specialize” in one location like FPC? looking at c++ code I
often see things like Vector<x> used in multiple locations instead of
declaring a single type (I have no idea why they would do that but it’s
very common). Maybe that’s why compile times are so slow?
C++ specializes once per compilation unit (and per unique type parameters).
FPC does this as well, but in addition it will try to reuse a compatible
specialization that's located in the interface section of a used unit.
