> I first ran into Tcl on Sparc stations in the mid 90s, and came away with the impression that it was just a bad language. I was implicitly comparing it to Perl To be fair, I think that Tcl really improved with 8.5 (apply, dict and no more expr). No idea what I would have thought of it if my first encounter had been way before that point. > I think there's room for a new language which speaks to Tcl's strength as a command language. As mentioned in the "Cons" section, have you looked at Rebol's revival https://github.com/red/red https://github.com/red/red?

My impression was a rather shallow one, between the language getting better and my understanding why it looks and acts the way it does, I'd say my change of heart is 20% the former and 80% the latter. The reasons I think something new would do well are things Tcl can't fix. Examples: leading zero octal, 0 is false, 1 is true, and it just... Tcl has a face only a mother could love. I've been interested in Red for years now without trying it out. It's very high-concept and sort of... totalizing? in a way which seems maybe unfocused. It is admittedly quite clean on the page, and there are some solid ideas there, one of these days I'll take it for a drive. One quibble is they need to stop punting to Rebol and write native documentation, being told that Red is "90% compatible" with another language no one uses, and getting shelled out to the documentation of that language, is not a great way to keep the funnel intact. But you have to, this is where the "official documentation" link sends you: https://github.com/red/docs/blob/master/en/SUMMARY.adoc https://github.com/red/docs/blob/master/en/SUMMARY.adoc That, combined with the "Red is all things to all people!" messaging, gives me the (perhaps unfair) impression that I would run into dusty corners and sharp edges fairly quickly if I tried to cash in the Ultimate Programming Language promise. Just finish up the docs, folks. Only have to do it once. I don't think it fits the new command language vision, however, because bare words are evaluated. In Tcl, the first word is special, and it's a command, everything else is strings unless you want to substitute in another string (or what have you). That strikes me as essential for this niche, notably this is how shell works and it's tough to imagine a usable shell which didn't work that way. But talk is cheap and a language implementation is very, very expensive. If I needed to add a command language to a program, I'd use Tcl and call it a day.

  Leading-zero-means-octal-number is one of the things which got fixed in Tcl 9.0, see https://www.tcl-lang.org/software/tcltk/9.0.html#tclchanges https://www.tcl-lang.org/software/tcltk/9.0.html#tclchanges - the subsection headed "Numbers".

    Hah! Old dogs can learn new tricks. That pleases me an unreasonable amount.
