Yes indeed, I concur completely with your comments. I've used Tcl/Tk for a few decades and for a long time enjoyed it's Lisp-like character. Of all GUI toolkits Tk is by far the best thought out, no wonder it's been adopted by a number of other languages.

Tcl does have a few disadvantages, for one the lack of distinction between string and list types makes certain programs hard to write. Also the absence of lexical environment for the apply command requires awkward workarounds. Many Tcl users dislike expr syntax.

Warts notwithstanding, Tcl has allowed me to be very productive. Over the years it's been steadily improved, and yet remains mostly compatible with code written even decades ago. That's a rare accomplishment in the programming universe.
