[RMS faults Tcl for its linked-lists-lessness. Explain what linked lists are, who RMS is, and Tcl perspective--mostly that Tcl doesn't need 'em.]
Arjen Markus I do not know who RMS is, but "woe , ye of little imagination", Tcl lists can be used as linked lists - if you regard a linked list as some abstract data structure (apart from the implementation!). I regard his/her statement as an example that most people can not distinguish implementation and concept!
RS RMS is Richard M Stallman, a famous programmer in the GNU scene, but not enthusiastic about Tcl.
