           Summary: reimplementing methods for interface
           Product: D
           Version: 0.173
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: benoit tionex.de


http://www.digitalmars.com/d/interface.html
A reimplemented interface must implement all the interface functions, it does
not inherit them from a super class:

interface D{
    int foo();
}
class A : D{
    int foo() { return 1; }
}
class B : A, D{
    alias A.foo foo; // shouldn't this work for the reimplementation ???
}

in DMD 0.173 it doesn't.

This is as designed:

"A reimplemented interface must implement all the interface functions, it does
not inherit them from a super class:"

The quotation says nothing about whether this is valid code.  It merely states
_that_ a class that reimplements an interface must implement the interface
functions, not _how_ it may or may not go about doing so.

Hence the comment,
    "shouldn't this work for the reimplementation ???"
i.e. shouldn't this be one way to go about implementing the interface
functions?

Reopening per lack of response to my last comment, and considering that it's
been brought up again.

An alias is not an implementation.
