[[Now, here's a challenge. Discuss what an "object" is, from a Tcl
point of view!]]

An object, from an [object orientation] point of view, might be thought of as an entity within an application which has executable code as well as related data and state. 

It is, generally (always?) a specific instantiation of one or more [class]es.

See also '''Object (Computer science)''' [http://en.wikipedia.org/wiki/Object_%28computer_science%29]
at Wikipedia.

Other kinds of ''object''s related to Tcl are:

   * [Tcl_Obj] - the fundamental representation of strings, etc. in Tcl ''([DKF]: Note that it probably should have been called `Tcl_Value`, but that was taken for something else now obsolete.)''

I don't recommend using any other object system than these if you want anything even vaguely "objects and classes" conventional.
