Comprehensive and Detailed Explanation From Exact Extract:
* An interface reference (go_if1) can point to any object of a class that implements that interface.
Therefore, creating an instance with NEW cl1( ... ) and directly assigning it to the interface-typed variable is valid (A).
* Type inference with NEW #( ... ) cannot infer a class from an interface-typed target (no unique implementing class), so (B) is invalid.
* An interface reference exposes only the interface's methods; it cannot call class-specific methods (so (C) is invalid).
* Calling interface method m1 via the interface reference is valid (D).
* From the class reference, the interface method can be called (implicitly or explicitly qualified) as go_cl1->if1~m1( ... ) (E).
This reflects ABAP OO rules in ABAP Cloud (method visibility via static type, interface implementation, and explicit interface method calls).
