Oh my god. Oh my god??
So in this post https://mastodon.social/@mcc/114169299830195223 i freak out at the fact my first-attempt 110-line LISP evaluator written off the cuff mostly worked. Then I realized it couldn't do nested expressions or function calls. Fine. Nesting turned out to require real changes!
Looked at function calls tonight
FUNCTION CALLS ALREADY WORKED. It worked when I made that post on the 16th. What didn't work was *tab characters*. By coincidence, my only test file containing a tab was the fn test.
