<p>For "Week 5" I did TCL, and it kind of set my brain on fire with "wait… you can just DO that?".</p><p>In TCL, strings are anonymous functions and vice versa. In my old Emily language, "if" and "while" blocks were implemented by passing in lambdas; but in TCL you do the same thing by *passing in a string containing {the code to execute}*. I started trying to imagine what "hygienic" TCL would be; if TCL is a C macro, I want an ML or Rust macro. I tried to imagine something closer to LISP than TCL.</p>
