Major decision: Result of the slice will be critcl 4, and require Tcl 8.5 to run itself. Still be able to generate packages for Tcl 8.4.
To much nice stuff to be had, and simplifications.
- Can drop the dict84, lassign84 packages.
- Can drop "lappendlist".
- Can get rid of more eval/linsert combos.
- Ensembles make the command import shorter.
- apply for initialization code.

Started on moving packages over.
As part of that the packages get debug narrative added as well.
