-class ``Foo`` has class-level storage vars ``bos_class__Foo__$thing``
+next bits…
 
-* ``bos_class__${class}__isa``
-* ``bos_class__${class}__meta``
+* fix all the ``*-into`` functions/methods to take the destination
+  variable name as 1st argument (otherwise optional arguments become a
+  mess)
 
-``invoke $class $id $method @etc`` if ``$class/$method`` is defined,
-call it; otherwise delegate to the meta-class
-``bos_class__${class}__meta`` by calling ``$metaclass/invoke $class
-$id $method @etc``
+* expose namespace open/close, and ``namespace $name; do …; done``
 
-then we have ``bos/mop/base/invoke`` and
-``bos/mop/base/find-method-into`` and
-``bos_class__bos__mop__base__meta="bos-dispatch/invoke bos/mop/base 0"``
-so its metaclass instance is an instance of itself
+  - use them inside ``class_open`` / ``class_close``
+
+* formalise that ``bos-dispatch/invoke $class 0 $method $args`` is a
+  class method invocation
+
+* ``bos/mop/base`` + ``bos/mop/inheritance`` become ``bos/meta/class``
+
+* add ``bos/meta/attribute``
+
+  - store values in ``bos-namespaces/store-*-for-into attribute
+    $attrname $defining_class $object_class $object_id`` (notice, we
+    also need the class that owns the attribute, not just the class
+    that generated the object, because attributes are local to the
+    class, they're not inherited!)
+
+  - ``get-value`` / ``set-value`` methods
+  - add name, type, owning metaclass as attributes to itself
+
+* add attribute support to ``bos/meta/class``
+
+  - ``find-attribute-into``
+  - ``add-attribute``
+  - add class, mro, as attributes to the metaclass
+
+* store class→metaclass association somewhere (global dictionary,
+  probably)
+
+  - when creating a class, create a metaclass instance and store it
+  - the store must be pre-populated with metaclass instances for:
+
+    + ``bos/mop/class`` → ``bos-dispatch/invoke bos/mop/class 1``
+    + ``bos/mop/attribute`` → ``bos-dispatch/invoke bos/mop/class 2``
+
+    and those instances' attributes must be manually stored
