Foo<@baz> is not a value either, but a container. I would say that
Foo<$.baz> returns a generic container that happens not to work
without an extra instance argument to say which chunk of data to map
the container metainfo onto.
: Should it return some kind of meta-object?
Yes.
If methods and subs are in the same namespace, and both have the &
sigil, what about instance attributes and class attributes? Is this
legal?
class Foo {
my $.bar;
has $.bar;
}
Part of me thinks that it should be since my $.bar is an attribute of
the Foo class, and has $.bar is an attribute of instances of Foo.
Also, is there anyway to iterate over the keys in the namespace? The
old way would be to do something like keys(%Foo::). Is something like
this possible with the new way?
Thanks,
