Ruby way to say this?

How about:

    def if_zero(exp,alt)
      exp == 0 ? alt : exp
    end

    x = 0

    if_zero( (x+=1) + 1, 7) # => 2
    if_zero( x-=1 , 8) # => 8

So your original would look like:

    # if_zero(one_thing, other_thing)

Let's make that more OO-pretty (using a goofy name):

class Numeric
  def or_if_zero( alternate_value )
    self.nonzero? ? self : alternate_value
  end
end

Which makes the code:

oneThing().or_if_zero( otherThing() )
