/**
 * @assertion If more than one extension applies to a specific member
 * invocation, then we resort to a heuristic to choose one of the extensions to
 * apply. If exactly one of them is "more specific" than all the others, that
 * one is chosen. Otherwise it is a compile-time error.
 *
 * An extension with [on] type clause [T1] is more specific than another
 * extension with [on] type clause [T2] iff
 *
 *   1. The latter extension is declared in a platform library, and the former
 *      extension is not
 *   2. they are both declared in platform libraries or both declared in
 *      non-platform libraries, and
 *   3. the instantiated type (the type after applying type inference from the
 *      receiver) of [T1] is a subtype of the instantiated type of [T2] and
 *      either
 *   4. not vice versa, or
 *   5. the instantiate-to-bounds type of [T1] is a subtype of the
 *      instantiate-to-bounds type of [T2] and not vice versa.
 * @description Check that there cannot be extension method invocation for the
 * receiver of type [dynamic], no matter which extensions are in scope.
