Years after encountering this in Chesterton, I read The Soul of a New Machine, and found Tom West quoted as saying "Not everything worth doing is worth doing well." I don't know whether he had read Chesterton or whether he simply made an obvious additional turn on a turn of phrase.
You're welcome. When you read it, consider that the team originally wanted to build a machine with a VAX-like instruction set, and that those fell out of fashion soon after. I did used to know Eclipse assembler, and it had its peculiarities--no register-relative byte addressing, as I recall.
