Note that I'm talking about Oberon+ (see http://oberon-lang.ch), not the good old Oberon (which has no generics at all); but also the latter was conceived as a general purpose programming language; it was its fate that Wirth and Gutknecht built an operating system with it first and there was a compiler only for that operating system, which was not ideal for the spread of the language. Go is the most famous offspring of Oberon so far.
