Huh? That's certainly not what I thought I was saying. I was saying that a
reason I thought it was important to be able to test type categories (what
Guido calls "look before you leap") was for implementing multiple dispatch.
In other words, an idiom which most people agree is usually a bad choice
for user code might be a great choice for a generalized library or language

It's pretty hard to see how you could construe my remarks as asserting some
interpretation of what you were saying.
