It's up to you.

That's normal.

The disambiguation constraints provide a bunch of constraints, and but only
the ones that resolve ambiguities are used.  The (assoc ".") being
together with other things, indicates not only that "." should be
associative (in case of ambiguity) but also its relative precedence
w.r.t other elements like , and =.
