Sticking a tri-state value (current, non-current, error) in a boolean
does not seem so good. We could go with an enum instead, but this will
be less convenient to use. So I'm not really sure which way to go :(

This needs to come in alphabetical order or make syntax-check will fail.
Looks good otherwise.
