Comment (by robertwb):

 It's backwards incompatible because if some objects (defined within or
 outside of Sage) define sgn() and others define sign(), removing this
 aliasing would cause one or the other break.

 If we decide to go this route, I think it should be a separate ticket than
 this performance enhancement.
