These days Tcl has a small but enthusiastic following. This year's European Tcl conference just happened, see https://openacs.org/conf2024/info/ . The 9.0 release of Tcl and Tk is coming soon - https://www.tcl-lang.org/software/tcltk/9.0.html .

A while back I wrote a blog post about why I think Tcl is special - https://colin-macleod.blogspot.com/2020/10/why-im-tcl-ish.ht... .
