The first didn't work due to the very low precedence of the 'and'
operator. This should work:
  return self == t2 && self != t1

Although (living with Lua these days) I like the english 'and' and 'or'
operators better than their C-style && and || counterparts, in Ruby I
advise using && and || exclusively, or else be prepared to start
slapping parentheses all over the place.
