I love TCL. The author points out my favorite aspect: "it has a radical minimalism". I use it for hobby projects because I work in Python all day professionally and like to mix it up a little in my free time. It feels very different but inhabits the same use case space. That being said, here are some interesting things that tripped me up: - using expr for arithmetic. The author mentions it, and it is cumbersome, but it also exemplifies what makes TCL special - upvar for pass by reference. TCL does pass by reference by the command upvar, which says "take the variable named x in the scope above and assign it to the variable y in this scope". Confusing at first but a nice way to have pass by reference in a dynamic language - docs are hard to read sometimes. The manual and tutorial for TCL are fantastic; the wiki is a little hard to read sometimes. The pages kinda seem like conversations, with authors weighing in on an article and tagging their names to their comments. - lack of structured data. Saw another commenter posted this, and its something I wish TCL had better out of the box support for. The addition if dict was huge. The good news though: it's extremely easy to build a new command set to build a data structure out of dicts. Despite all of this I'm a big fan of TCL. I try to tell as many people I can about it, because it really feels like a breath of fresh air compared to my day job Python. It allows you to be creative (and reckless!) with its power. Edit: going to post the tutorial because it's so essential to getting started: https://tcl.tk/man/tcl8.5/tutorial/Tcl0.html https://tcl.tk/man/tcl8.5/tutorial/Tcl0.html
