IMHO this should rise a compiler error:
---
mixin template T() {
    override string f() { return "T"; }
}

class A {
    string f() { return "A"; }
}

class B: A {
    mixin T;
    override string f() { return "B"; }
    mixin T;
}

void main() {
    A b = new B;
    assert(b.f() == "B"); // This passes
}

Or, if this shouldn't rise an error, this also should compiles:
---
class B: A {
    mixin T;
    mixin T;
    override string f() { return "B"; }
}
---
Error: function main.B.T!().f multiple overrides of same function
