Enclosed log evaluation is really nice and I'd have some trouble going back. It's older than Elixir, too; Commons.Logging in C# has supported it for a long time and most logging frameworks in Scala take a call-by-name parameter rather than an evaluated arg. |

The '=>' means call-by-name in Scala, the argument is lazily evaluated.
