a common problem for me is that i'd like to add just a few features
to an already established class. how can i do this in the simplest
manner?

i can ...
(1) make new-class a class with a single member of type base-class.
(2) make new-class a derived class from base-class with no members.

then i can add the new functions to new-class that i want. the problem
is that i have to do a lot of useless bookkeeping to pass all of
the features of base-class (member functions, friend functions, etc.)
on to new-class whichever of these two techniques i use.

am i missing something? if not, why isn't there an easy way to do
this in c++?
