Oh I see. This is best solved in the language - a function type F1 should be
implicitly convertible to another function type F2 if all of F1's parameters
are subtypes of the corresponding parameters in F2.

Arrays of const are a subtype of arrays of invariant (and actually this is
another feature that is needed in a number of places), which takes care of the
case in point.

So I hereby assign this to Walter. :o)
