[Issue 2525] Can't use `override` when implementing abstract base class's interface function

[via Digitalmars-d-bugs]

--- Comment #14 from Martin Nowak <code at dawg.eu> ---
As a workaround one can redeclare the interface methods in the abstract class.

----
interface I
{
    void foo();
}

abstract class A : I
{
    override void foo();
}

class B : A
{
    override void foo () {}
}
----

Note that this bug and the workaround also applies to implicit abstract
classes.

----
interface I
{
    void foo();
}

class A : I
{
    abstract override void foo();
}

class B : A
{
    override void foo () {}
}
----
