If they had different meanings, a simple rename would solve the problem. 
They have the same meaning.

One possible solution being encapsulating an object instead of 
inheriting from it?

Fortunately, I can change all of the classes, and extracting the common 
parameter into a common base class worked.

Problem solved. Thank you for all your help!

Cooperative classes are fantastic! :-)
