Another quick one.  Trying to tease out a firmer meaning for "everything
is an internal rep".  Should I think about that as being similar to
the ClientData values Tcl makes use of all over the place?

Summary of ClientData features:

A way for some bits to get passed to Tcl, held by Tcl for a while,
and then passed back.  The whole time Tcl does nothing with them,
has no knowledge of their format (beyond size), doesn't change
their value, and if it has reason to need to lose their value,
calls back so the ClientData owner can react to that.
