Simplifying somewhat (ok, a heck of a lot), an rvalued:
$foo is bar
or
$foo : bar
is syntactic sugar for:
bar($foo)
with some extra magic for handling a properties hash
associated with $foo's value, in particular resetting the
hash when $foo's value changes.
Right?
Basically, p

I think the idea was "class".
Lexical namespaces can just mirror whatever happens to the rest of the
package/class system.

Well... "package" is a magic perl5-inducing keyword in perl6, right?
Maybe "namespace" is the way to go.

Not sure; probably... but we'd need not just *nested* namespaces,

That is a very unhelpful attitude.
Give me data aggregation by inheritance, namespace scoping, and

tack on.
