Wait, you're not talking about constructors here. You're talking about the idea of giving a class a parameter list? A feature that I independently came up with about 7 years ago, before I - or most other people - had even heard of Scala? And then implemented 5 years ago as one of like the very earliest features in the Ceylon type checker? And which is not actually the topic of the linked blog post? You're calling me out for copying that?!

Man, seriously, there is such a thing as two people coming up with the same good idea independently. If you can't imagine such a thing happening, I'm at a total loss.
