Thanks Fred,

An insightful response. Where do you see behaviours in all this?

The context is that I've recently advocated introducing behaviours
very early on (not full gen_* behaviours), but just as a really simple
step in learning erlang, same as adding tests, using typer & dialyzer,
in helping enforce API contracts between modules. It seems to ease the
shock of the first encounter with gen_server etc, removing a bit more
of the black magic up front.

A+
