inheritance is confusing and obscures the control flow in programs, that
it was often mis-used, and that while there are still legitimate uses
cases for it, it should be used sparingly.  That helps quite a lot.

C++ templates let you write generics that are often cleaner than using
subclasses, though the design of templates can lead to awful code and
notoriously bloated and useless error messages.  The long-awaited
Concepts extension should help some with that.  Again though, like
anything else, templates work best when used tastefully rather than
