Misleading ByRef Parameter

Flags the value-parameter of a property mutators that are declared with an explict ByRef modifier.

Reasoning

Regardless of the presence or absence of an explicit ByRef or ByVal modifier, the value-parameter of a property mutator is always treated as though it had an explicit ByVal modifier. Exception: UserDefinedType and Array parameters are always passed by reference.
