Ah, I misunderstood then, so a warning/error will be raised if no precedence
exists? Thanks for the explanation! I’ll probably still favour overkill
brackets, but this makes sense.
In any event I’m on +1 for the more standardised syntax and the switch to using
#directives, makes a lot of sense since these are really just customisable
compiler symbols.
