class curry:
  def __init__(*args, **kwargs):
    self = args[0]
    self.function = args[1]
    self.args = args[2:]
    self.kwargs = kwargs
  def __call__(*args, **kwargs):
    kwargs.update(self.kwargs)
    return self.function(self.args + args, kwargs)

faren2cel = curry(conv, b = -32.0, c = 5.0 / 9)
