Consider the following example:

import fire

def test(a=1, b=1):
  """
  Returns the sum of a and b.
  
  :param a: The first parameter
  :param b: The second parameter
  """
  return a + b
  
fire.Fire(test)

If the file is called using python ./myFile.py --help, the help signature is printed as expected

However, if **kwargs is added to the signature of test, the return value of the function is printed instead. Is this expected behavior? It works if I run python ./myFile.py -- --help, but for someone using my application and not familiar with the 'fire' CLI, this is non-intuitive.

How do I need to modify test so that if someone calls --help on it, the help signature is printed?

Thanks!
