I'm still afraid of the following scenario: Eventually, people might
regard "RPython plus type declarations" (or something similar) as
first-class Python because it's faster and runs on more
implementations, so they try to stick to it.  So effectively you
would have changed Python.

Maybe I misunderstood something because I could not follow all of
Kay's text but I think one should not change Python or create a
look-alike to allow for better implementations.  The language should
fit my brain rather than an implementation.

Tschö,
Torsten.
