If the purpose of developing classes is for code re-use and inheritance, then VFP should not override by default. This would also be useful when using third party classes...

It was designed that way so you wouldn't have to think about it. DODEFAULT() and the Scope Resolution Operator (::) are provided to access parent code.

Subclassing objects targets more the reuse of the entire class rather than just method code.
