The idea (at least for my part) is that the run-time reflection should
be based on the static meta-objects and mostly implemented
as a library on top of them with some additional trickery if necessary
(similar for example to typeid to allow reflection of polymorphic objects).
Maybe Dean can clarify his ideas better, but we have agreed on
the "desired features" as described in 3.1 in the paper and also
on that everything that can be provided at compile-time should
be provided at compile-time (including even strings like identifiers,
keywords, etc. if possible).
