The linked FAQ specifically talks about returning pointers to structs that fulfil the 'error' interface and why it's a bad idea.

Typed vs untyped nil means that, in practice, all functions must return an error of type 'error', and force clients to downcast at runtime:

Of course, there are ways around this such as returning a struct, but then that's no longer compatible with the error interface.

The letter 'M' in the Roman alphabet is derived from the symbol for running water in phonecian, and the letter 'A' is a rotated cow's head.

Phonecian is partly derived from Egyptian hieroglyphics. I love this stuff.
