Playing around, I've been trying to figure out the most pythonic way
of incrementing multiple values based on the return of a function.
Something like

  def calculate(params):
    a = b = 0
    if some_calculation(params):
      a += 1
    if other_calculation(params):
      b += 1
    return (a, b)

  alpha = beta = 0
  temp_a, temp_b = calculate(...)
  alpha += temp_a
  beta += temp_b

Is there a better way to do this without holding each temporary
result before using it to increment?
