Go supports a slimmed-down version of OOP compared with Java/C# via property and method "promotion". There are no static properties/methods and no abstract classes but you have interfaces with Ruby-esque duck typing. I've omitted generics as that's due in Go 2.0. I find listing methods beneath their corresponding struct definition to be quite adequate when OOP is the best fit .... which isn't that often. I just finished implementing most of the functionality in Matt Zandstra's "PHP Objects, Patterns, Practice", 5th edition, in Go and didn't miss much.
