New comment by mfex in "Dutch Railways offers unlimited off-peak train travel nationwide for €49/month"

This special ticket is implemented by providing a 2-month discount on the existing 'off-peak free travel' subscription from the Dutch Railways. This was deemed the only way to quickly introduce such a product [1].

After this was posted here in 2017 I made a version in ClojureScript, where you fly over Amsterdam instead of Pittsburg.

There are 2 speculative fiction books about nuclear war unfolding in present time. Both feature usage of the 'football'. The 'commission report' is my recommendation out of the two:

Re: 1. In your Scala example the two underscores are placeholders for two different arguments. The underscore is also used in Scala for catch all clauses with 'match'. How is this syntax then way better than %1 and %2 for arguments in shorthand syntax in Clojure?

New comment by mfex in ""Introduction to Monads" with Clojure (video)"

mfex — Fri, 09 Apr 2010 12:11:13 +0000

The two monad tutorials referenced in the talk and the clojure.contrib.monads source explain monads in the same way:

http://onclojure.com/2009/03/05/a-monad-tutorial-for-clojure... http://intensivesystems.net/tutorials.html

The onclojure tutorial shows how (let ..) and (for ..) expressions are all about nested functions and how you can construct them yourself with monads. Be sure to work through it to part 4 which shows an elegant solution using monads for the Monty Hall problem, which is about probabilities and distributions.
