           Summary: double inheritance from the same interface
           Product: D
           Version: 0.172
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: roel.mathys gmail.com


In the docs it says twice inheriting from the same interface is not allowed.
But DMD accepts it and compiles it.

Example code:

import std.stdio;

interface C
{
        void f();
}

class CC : C,C
{
        void f() { writefln("hello"); }
}

void main()
{
        CC cc = new CC();
        cc.f();
}

There's even a direct example of this in the spec, which DMD allows:

interface D
{
    void foo();
}

class A : D, D  // error, duplicate interface
{
}

(Of course, this doesn't compile also since foo() isn't defined in A.)
