I too like Python but, unless I'm missing something horribly obvious here, it doesn't appear that much different than how Python does it.. they use ":" instead of "=". The "**" syntax is identical to Python AFAICT.

Ruby
def cycle(first_value, *values)
  options = values.extract_options!
  name = options.fetch(:name, 'default')

Python
def cycle(first_value, name=default):

or alternatively

def cycle(first_value, **values):
  name = values.get('name', 'default')

Both Python versions looks much simpler to me.

That's the old way of using keyword arguments. The new way, as the article points out:


# Ruby 2.0:
def cycle(first_value, *values, name: 'default')
  # ...
end

Ooops, you're correct, I read that article too hastily. In this case I'm glad to see sane syntax being used consistently.
