Piers Cawley:

Monads are a generalization of this principle; in a sense, the details of how they work are irrelevant (in the same way that the innards of an ordered pair are irrelevant), what’s important is that they provide a box in which ordered execution can happen. And ordered execution is what you need if you want to write code that uses side effects or works with impure ‘functions’ that don’t always return the same value given the same input.

Monads; one of the things I’ve always wanted to spend some time understanding, but never found the time to do … this will suffice for a while.
