Created attachment 874 Code demonstrating the issue. Overriding a function in a base class with the same parameters, but different qualifiers on those parameters (such as const or immutable) causes an error, even if the parameters are value-type parameters.

This is contravariance for parameters, and is not going to happen. See Walter's comments in issue 3075.
