Sure, I appreciate that!

If you're looking for other ways, I also had an older one, which I
thought just had to be faster (using multiple inheritance and
is_base_of), but at least for my purposes it did not make a difference:

https://github.com/rbock/sqlpp11/blob/0.8/include/sqlpp11/detail/set.h

I'd be interested in how that implementation performs in your tests, too :-)

Looking forward to that :-)

Thanks and regards,
