[[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. (See [Who says Tcl sucks...]) I also have problems understanding the need for linked lists - Tcl's are contiguous in memory, so the benefit of links, i.e. iterating over it, is easily reached with [foreach]. OTOH, recursing over lists involves copying in Tcl, so real links like LISP's CAR/CDR also have their advantages.
