Another option is std.conv.emplace:

void method(bool flag) @nogc

    if(flag) {
        obj = emplace!MyClass(buffer, 1);
    } else {
        obj = emplace!MyClass(buffer, 2);

    // Unfortunately, destroy() is not @nogc

Thank you for clarification. But I have one more question. Do I 
have to use destroy for deallocating object from stack?
