CoffeeScript feels for me like more flexible Python. Only thing I was missing until ES6 were generators.

I simply love how I can wrap line from csv file in custom CoffeeScript object just by declaring class like:

    class Entry
      constructor: ([@id, @description, @amount]) ->

and doing new Entry(line.split(','))

View on HN

An equivalent in Python is

>>> Entry = namedtuple("Entry", "id description amount")

>>> Entry(*line.split(','))

Entry(id='1', description='an entry', amount='99')

Neat, but can I add few methods to my Entry touple?

Can it inherit from something else?

Can something else inherit from Entry?

Won't named touple have some of its own methods that my methods could have collided with?

You can use a `namedtuple` class as a base class, e.g. like this:

    class Entry(namedtuple('Entry', ('id', 'description', 'amount')), SomethingElse):
        def more_methods(self):
            pass

Thank you for this example. It's exactly the thing I had with CoffeeScript

>Neat, but can I add few methods to my Entry touple?

Yes, if you subclass it.

> Can something else inherit from Entry?

Yes, it can be subclassed.

>Won't named touple have some of its own methods that my methods could have collided with

Yes and no, it has the "index" and "count" methods any tuple should have, which can easily be overridden by specifying them as attributes in the second argument to the contructor, through reassignment during initialization or method overriding.
