Not a problem, since the convenience of ADL is lost already. :)

The operator overloads require the user to use "using" anyway; like
those overloads, at<> would use SFINAE so it won't clash with anything
the user may have defined. I'm pretty sure I've never used "use" so
many times in a single sentence :)
