           Summary: Templated interfaces not matched
           Product: D
           Version: 2.012
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: caron800 googlemail.com


The following code won't compile:

    interface J(T) {}

    class A : J!(int) {}

    void foo(T)(J!(T) j) {}

    void main()
    {
       A a = new A;
       foo(a);
    }

The error is:
foo(T) does not match any function template declaration.

And yet it does. Change main to

    void main()
    {
       A a = new A;
       foo(cast(J!(int))a);
    }

and it compiles just fine. I contend that the explicit cast should not be
necessary.

Increased severity to major, as this issue is blocking progress on Phobos
development.

This is related to #1715, I think -- at the very least, this would be a
workaround for #1715 and #1714 if it worked.

The patch in bug 4173 also fixes this.
