I've used it effectively for decades and never had any problems.

I'm not advocating ADL necessarily, I can see the complexity; but we need an effective response though. D has made the patterns it supports somewhat more attractive than they are in C++ (mainly thanks to UFCS), yet the local imports shadowing overload sets issue is confusing and unintuitive, and makes the situation fail completely.

For my money, SFINAE is the most egregious bit of the C++ spec. (though we're not doing a whole lot better!)
