Created an attachment (id=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.
