I'm not a big functional programming fan, so it should not come as a
surprise that I don't often use lambda. The one place I do use it is in
unit tests, where assertRaises() requires a callable. If what you're
testing is an expression, you need to wrap it in a lambda.
I suppose you could call this a special case of a callback.
