* @assertion We define inherited(J, K) to be
* the set of members m such that all of the following hold:
* • m is accessible to K and
* • A is a direct superinterface of J and either
* – A declares a member m or
* – m is a member of inherited(A, K).
* • m is not overridden by J.
* ...
* Otherwise, if the static types T1,...,Tk of the members m1,...,mk are not
* identical, then there must be a member mx such that Tx <: Ti, 1 ≤ x ≤ k for
* all i ∈ 1..k, or a static type warning occurs. The member that is inherited
* is mx, if it exists; otherwise: let numberOf P ositionals(f) denote the
* number of positional parameters of a function f, and let numberOf
* RequiredParams(f) denote the number of required parameters of a function f.
* Furthermore, let s denote the set of all named parameters of the m1,...,mk.
* Then let
* h = max(numberOf Positionals(mi)),
* r = min(numberOf RequiredParams(mi)), i ∈ 1..k.
* Then I has a method named n, with r required parameters of type dynamic,
* h positional parameters of type dynamic, named parameters s of type dynamic
* and return type dynamic.
* @description Checks that there's no static warning if non-abstract class
* implements two interfaces with same named methods that have different named
* formal parameters and defines method from its implicit interface. In this
* case the implicit interface of non-abstract class has method with one
* required parameter of type dynamic and a set of all named optional
* parameters.
