>What I found most interesting about Tcl was its capacity for metaprogramming, due in large part to its quoting mechanism. Cool. Ah yes, memories coming back a bit now. (Had read both the Ousterhout (Tcl and Tk) and Libes (Expect) books years ago.) I remember that though the Libes book is about Expect, he does go into talking about Tcl a lot, including some of the advanced features you mention (though always or a lot, in the context of how they are used in Expect). I guess part of its (Tcl's) dynamic nature comes from the fact that everything in Tcl is a string (and the quoting and the ability to evaluate expressions), like everything in Lisp is a list (or an atom).
