You can split the polymorphism situations into 2 types:
1) Those with consistent types and
2) Those that require different types
For (2), runtime polymorphism doesn't work. For (1), it can be coded
as static polymorphism, then a single type erasure layer can be easily
written (with an abstract base "interface" class and an
"implementation" class template) that adapts the static classes for
dynamic polymorphism.
So why wouldn't I just write everything as static, then apply the
erasure layer at the level appropriate for my application, if needed?
