A prefix is never contravariant. Even if say p.A is used in a contravariant context, we cannot assume contravariance for p because p's lower bound might not have a binding for A, since the lower bound could be Nothing. By contrast, covariance does translate to the prefix, since we have that if p <: q then p.A <: q.A, and well-formedness requires that A is a member of p's upper bound. Overridden in OrderingConstraint's ConstraintAwareTraversal, where a more relaxed scheme is used.

Can the prefix of this static reference be omitted if the reference itself can be omitted? Overridden in TypeOps#avoid.

Returns a string representation of the object.

The default representation is platform dependent.

The type parameters of the constructor of this applied type. Overridden in OrderingConstraint's ConstraintAwareTraversal to take account of instantiations in the constraint that are not yet propagated to the instance types of type variables.
