Actually, no, it isn't, because...

... obviously the syntax description itself is evidently broken (at
least in the v3.6.1 incarnation).

Most notably, `MOD_EXPRESSION` is used in `FACTOR`but isn't specified
anywhere.

Just to knock you off your perch.


That said, "as designed and documented" doesn't necessarily mean that
it's free from issues that might warrant fixing. It might just be that
there's a problem with the design.

And I for one would argue that that's indeed the case (presuming dot
notation has been excluded from functions by design rather than by
oversight). Because - evidently - this behaviour goes against user
expectations.
