The problem is that it's much easier to put
a class in an ADL blocking namespace, than to
put a class in al ADL blocking namespace:

namespace bind_adl_block
{
     template<class F>
     void bind(F f);
}
using bind_adl_block::bind; // bind can still be found by ADL

The only way to do it is with a using
directive:

using namespace bin_adl_block;

but this is fragile for other reasons.
