It is not required and probably shouldn't, or at least shouldn't 
in many cases.

This problem is the exact same one as strongly typed vs 
dynamically typed languages, except at compile time. And solution 
are the same: interface (concepts) or duck typing and hope for 
the best.

The end goal is pretty much the same: writing reusable code. The 
implementation differs, performances as well, but that is pretty 
much it.
