Last night, while under the full belief that I could write a very simple lisp interpreter, I was awake until stupid o'clock and to my credit I got the tokenizer working and produces an output of parsed code. It's really basic but I was pleased to have gotten anything correctly parsed at that time.

But I'm also sitting outside my apartment waiting for a locksmith because lack of sleep left me unprepared to function correctly today and I'm now locked out...

Well done me!
