Actually I was thinking that MyClass.isa(...) would work much as it
did in Perl 5 (like an instance). But that access to the underlying
MyClass class instance would not be as simple. Something like
::MyClass would provide access to the Class instance.
class Foo {}
Foo.isa(Object) # true
Foo.isa(Foo) # true
Foo.isa(Class) # false
::Foo.isa(Object) # true
::Foo.isa(Class) # true
::Foo.isa(Foo) # false
However, this is not speced anywhere, so I am just really making stuff
up out of my head :)
I've always thought Foo and ::Foo were synonyms (except maybe in
signatures, but that's another thread). I.e.:
Foo =:= ::Foo =:= ::("Foo"); # true
And all of these are (except if you do metamodel hackery) Class
objects,
i.e. the following all work and are semantically identical:
my $foo = Foo .new;
my $foo = ::Foo .new;
my $foo = ::("Foo").new;
Am I wrong?
Probably not, it is more likely that I am wrong :)
However, this does bring up the point of how one can access the
class(Foo), meaning the instance of "Class" which represents Foo.
I for one think whatever it is it should involve a colon :P
