I got little scars from knowing precedences and then switching languages. I also got them from short-testing booleans that later turned into T|boolean. And all these clean just_p’s incrementally evolved into !just_p ? !un_q : t’s. Because I was flying through a mass-change after a day and had no mental capacity to repack the meaning of the previous expression and retain the context of a changeset.

Crystallized syntax is clear, but also extremely fragile, if you take humans into account. We have limits. Everything pushes us to these limits. Any complexity spike that overlaps with secondary complexity or fatigue is above our limits. That’s where we make mistakes.
