This also allows you to do a complete null check in a single statement:if (maybe(tree).left.right.right.left.right !is null) { // do something with that value } If nothing else, this at least saves you the trouble of having to check every intermediate reference in the chain. :)
Very clever, this should go straight to std.typecons. I'm definitely ripping it for my project, if you can just scratch something like a boost license on it ;)
