Hi.

For what it's worth, my point of view:

Full support for the braces, but please *do*not* allow both ways. Why? 
Perl's "more than one way to do it"? If there's one way, it's clear what 
to use. I see absolutely no point in this. Really. Please don't.

Fine with me. I'd use ::Foo for internal classes anyway to avoid speed 
and ambiguity issues.

We roll everything in classes anyway, so fine with me.
