Why not = add literal operator templates returning placeholders?

Why not deprecate std::bind? Generic lambdas provide a bette= r solution, and we don't benefit from having two ways to do the same th= ing.
=C2=A0
Compare:
std::placeholders::_1 = // old
1param // new

Would it cause a problem to add it in the global namesp= ace with no leading underscore? This saves the user a using directive and the name operator "= ;" param is reserved to the language anyway. It should still be= an ordinary part of the language, declared by <f= unctional>.

The name needs to be bikeshedded.
