As a long time C++ user, I’m curious why you like inheritance and virtual methods so much.

I maintain a medium sized, old-ish C++ code base. It uses classes and inheritance and virtual methods and even some multiple inheritance. I despise this stuff. Single Inheritance is great until you discover that you have a thing that doesn’t slot nicely into the hierarchy or when you realize that you want to decompose an interface (cough, base class) into a couple of non-hierarchically related things. Multiple inheritance is an absolute mess unless you strictly use base classes with pure virtual methods and no member variables. And forcing everything into an “is a” relationship instead of a “has a” relationship can be messy sometimes.

I often wish C++ had traits / or Haskell style type classes.
