I love tcl. My absolute favorite thing about it is that `man tcl` [1] gives a dozen paragraphs that
completely describe the language itself. Its simplicity always astounded me since it seems really simplistic but at some level it’s just as malleable as lisp. I wish it had caught on more (outside the hardware community which seems to have fully embraced it).
