I got the issue mentionned in the title, with the following piece of code (I
didn't succeed in reducing it further).

auto dispatch(
    alias unhandled = {
    }, V, T
)(V visitor, ref T t) {
        return t;
}

class Type {
}

class BuiltinType(T) : Type {
}

Type getPromotedType(Type t2) {

    class T2Handler(T) {
        Type visit(Type t) {
            return this.dispatch!(t => new BuiltinType!T)(t);
        }
    }

    class T1Handler {
        Type visit(Type t) {
            return (t => handleBuiltinType!int)(t);
        }

        auto handleBuiltinType(T)() {
            return (new T2Handler!T).visit(t2);
        }

        Type visit() {
            return handleBuiltinType!uint;
        }
    }

    return (new T1Handler).visit;
}

I have no clue what precisely cause the error.
