Privately?  I've read no posts that could lead you think what you wrote,
but (sorry to ask) you could always cite a post or two so I can read
what you are referring to.  By the way, if you are referring to the
recent threads about GC, he is sketching an incomplete (and, in my
opinion, unworkable) plan for compiler-assisted GC.

I'm disputing what *you* said.  I am happy that I know what he said,
though I am willing to be shown I'm wrong.
