Due to a long-standing bug in the Marmalade software, I was unable to upload the 1.3.0 release of Elpy to that repository in the last two weeks. For a discussion of this problem, see issue #196. To solve this problem, I have created a package archive specific to Elpy with the required packages that are not on GNU ELPA. To use this archive, add the following to your .emacs:

(require 'package)                                                              
(add-to-list 'package-archives                                                  
             '("elpy" . "http://jorgenschaefer.github.io/packages/"))

This is intended as a temporary solution, but I am not sure when I have the time to work on a longer-term one. I am sorry for the inconvenience in the last weeks.

It is impossible to correctly wait for multiple queues in Python and only consume the first element of any of them.

This came as a big surprise to me. Both because it seems like an operation that should be supported, but also because this never had been a problem in practice.

The first part of this series generated a lot of responses, both very positive ones and very negative ones. I’m quite happy to accept that I just don’t understand monads very well, but so far, no one was able to convince me of that. One of the negative responses claimed it was not possible to actually implement monadic structures using my (simple) definition, which I took as meaning that the idea I was trying to convey was not very clear.

This second part of the series will show an application of the explanation I gave in the first part. I’ll start with a concrete problem and implement it in Python, slowly building up to the ideas encapsulated within monads. I assume you to have a good understanding of Python to be able to focus on the new concepts introduced.
