The person whose 'complaints' I was stating says that DSLs (Domain
Specific Languages for those who, like me, were confused about the
acronym) are a big part of what he is after and one per interpreter is
fine by him. He also realises that the application(s) he needs them
for might be unusual. He doesn't specifically need the builtin types
to be extendable. It's just nice to be able to define a single class
in multiple modules. Even C++ allows this to some extent (but not as
much as he'd like).

He understands the implications of allowing open classes (import vs.
no import changes semantics, etc.). Personally, he doesn't care *too*
much about newbie safety since he's not a newbie. To quote verbatim:
"give me the big guns :-)"

And while we're at it, he also stated: "[...] add multiple dispatch to
your list of improvements for Python".

I hope this clarifies it a bit for other people.
