I did not insist on purity of the current fashionable style…
at the time I was rather annoyed and purity is for nazis.

• What you don’t use, you don’t pay for
• What you do use, you couldn’t hand-code any better

Error handling is not an absolute, there are many alternatives… (but people get emotional on that)

Coroutines
