I only know not to write things so complex because either I have made the mistake or some generation of someone I've learned from has made the mistake. It's not a logic problem, where the less complicated, better understood and more general rules of precedence allow writing equations that are terse, objective, and easily parsed by humans: it was born with C's invented, abstraction-breaking rules of precedence. You only learn it with a C-like language. What's a bit to a mathematician?

I'd argue the practices that are most popularly known as 'good practices' are to avoid mistakes that are common.

It took me a while to understand what you're saying. Please consider not using the condescending question marks.
