  icomment:   > it's not possible to make manipulations in place  What did you mean
              here under manipulations?

              That is expected in tcl, that some "static" code objects has a
              refCount greater as 1, despite you see this object only once, because
              of interp/namespace literals, code compiling etc.   Guaranteed
              refCount = 1 you're going to get, if it will be created and returned
              to interpreter inside any command, and will be used nowhere otherwise.


              Example:  proc test {} {  puts [::tcl::unsupported::representation
              [linsert {} end 1 2 3]]  puts [::tcl::unsupported::representation
              [string tolower DATA]]  }

              Furthermore you can always create a duplicate with refCount = 1, using
              function Tcl_DuplicateObj.

              Manipulation of object with refCount > 1 is allowed also, for example
              change to your own Tcl_ObjType (internal representation), but only if
              it string representation will be not changed or can be always
              regenerated to the same within your own Tcl_ObjType.

              An example for such "complex data structures" are objects contains
              file/channel/database "handles" etc.

              So long it's not clear as a bug, I will close this issue as invalid.
              Please provide more info if expected.
