std::bind vs ::bind ambiguity

[Paolo Carlini]

Hi,

> Any objections?

I believe to understand the issue and indeed have no serious objections, only, here - as in other similar cases for sure! - I'm a bit unsure about the correct constraining: should we require, for example pointer or class type?!? If I  keep in mind the famous 'do the right thing' in the containers, for example, it seems to me that we are moving from integer types as the most important class of types we want minimally to reject in C++03, to something wider and more accurate in C++0x.
