[ruby-talk:16066] Re: tryreturn - names and intentions

How about:

def getAValue
  result = methodOne || methodTwo || methodThree
  return result
end

Routines are called in seqeunce until a non-nil result is returned.

As for try____, if it works for you, by all means use it. That's one of the
great things about Ruby, it's malleability.
