of a class is part of the class members section and is not
global to the entire class metadata. This is crucial for
correct operation of functions expecting a base-class
metadata object.
That gives us the correct foundation to implement an
optimization under which generic arguments that can be
inferred from the 'this' pointer need not actually be
separately passed. This has the important result of
making all class member functions with the same signature
up to abstraction actually have the same physical
signature.

uncurrying level, which is something I find myself passing around
quite a bit. Make sure that it can propagate getter/setter
references in the same way.

the metadata objects for classes. This is currently only
done for methods defined in the main class body, and it's
(naturally) totally fragile, and it's screwed up in a
couple known ways w.r.t. generic classes: there's no
thunking when the overrider differs by abstraction from
the overridden method, and methods on classes currently
expect to get all the type arguments passed directly
and thus will disagree in signature from members of
non-generic classes. Also, of course, we're not using
any of this in the call infrastructure. But it's progress.
