Thank you for this, I'm unlikely to ever touch Erlang but looks like a fascinating read nonetheless.

It is a fantastic read. I find myself quoting section 5.3.1 on Well-Behaved Functions (WBFs) quite often, especially rule 2: "If the specification doesn’t say what to do raise an exception."

This really helps systems from muddling along into bizarre states, where things are going awry and nobody knows why.
