title: Bind pointer to member operators in C++
body: <p>What is the point of them?
  <br/>
  I've never used them for anything, and I can't see myself needing to use them at all.
  <br/>
  Am I missing something about them or are they pretty much useless?

  EDIT: I don't know much about them, so a description about them might be necessary...</p>
