Just an example: In Java the name clash is allowed. In the courses I attended many students confuse their variables so much that they think they must always prepend "this" to all member variables. So instead of prepending the parameters, they prepend the members. This is one of the most confused "features" of Java. I'm glad objfpc is less ambiguous than mode Delphi.
