#safe_send/#__safe_send__ ?
Quite honestly, I use #__send__ for a lot of things and I really don'twant to be \
bitten by a change here. I really like that "private" is anadvisory in Ruby, not a \
hard-and-fast rule. If we do change #send/#__send__, I would rather have a better \
name than#funcall (and is there #__funcall__?). Maybe: #unsafe_send/#__unsafe_send__ \
? What if we changed #instance_eval to specifically take a symbol:
  foo.instance_eval(:private_method, *args)
