Sorry, I'm not familiar with this statement.

No. Not about types. But I did have a point about OO. (Although, if you
classify types as the interface, then I suppose my point about Smalltalk
was incorrect. I merely mentioned it because I read your comment about
types, and immediately thought, "Smalltalk is not typed," per se.
Thinking about it. I think I was simply wrong about this. Sorry.)

But again, yes, I do have a point about OO.
