you can see the exact moment I get sleep-deprived by looking at my commit messages:

• add (. dict key) syntax special case to (set)
• add (lambda) tests
• fix interpreter stuff
• lots of changes
• more changes
• dfkjlnhfdlksjndfh

@kasdeya I've been known to swear in near-useless commits (usually from linters) that I'm going to merge into the previous commit.

@kasdeya
I thought I was the only one committing "lots of changes". Although I use "wawawawa" instead of that last one. You add a 'wa' for each consecutive hour you've been awake.
