We worked hard to make errors as understandable as possible, but
there's a point where you have to learn to use those messages. I'll
rephrase it for you: something is a ref but it should have been a
list. What could have caused this error? Well, CONFIG is a ref and we
are trying to lookup an associative list, it must be that liquidsoap
read !(CONFIG["ID"]) instead of (!CONFIG)["ID"]. Solution: make the
parentheses explicit.

In that case I don't think the error could have been much better.
However, it looks like the precedencies between ! and _[_] are not the
most natural ones, I should perhaps go change this. Any opinion on
this?

Cheers,
