Actually, ThreadLocation, which is very new - less than a week in cvs.

Note your followup is is a little unclear because you seem to use
"symbol" when you mean "binding".  Symbols are global and have no
mutable state - though Symbols can live in different namespaces
(packages).  Dynamic bindings are implemented using Location
objects, and they are mutable.  They don't necessarily have a
name.  An Environment maps a (Symbol, property)-pair to a Location.
The inheritance and other magic is all done at the level of
Environments and Locations; not Symbols.  (This is a change in
the last few months.)
