I don't mind your wanting to keep "the dot" free of too much connotation in
itself.

You're like saying: don't let the OOP campers take total control of "dot"
connotations. I'm OK with that.

For us, the OOP campers, there's a hierarchy of containment, such that
"dot" obeys an algorithm.

"If I'm not in you, I'll search your parent, and if not in your parent,
I'll search your ancestors" -- there's a widening radius, a search pattern.

Lawyers might understand: "if you can't pay the debt, maybe your sponsor
can" and so on, up the line (looking for deep pockets).

The positive angle: you, the new object, are free to inherit most of your
functionality and just need to specialize in these few ways.

That's a power of this notation: to assume predecessors.

Again: STEM fluency is the issue. If you haven't been exposed to dot
notation, that means 12 years of high school with no dissection of an
in-your-face web browser. Madness. Means you're not aware of your
immediate environment. Means your school is a joke.

To put it more concretely, if you use a web browser and yet your school has
no courses that help you learn JavaScript, then stay home and learn for
real, as if your future depends on it.

If your school offers no help with learning say JavaScript, then I'd say:

(i.e. "the teachers"), you the victim, the guinea pigs.

If your school is really so lax as to be devoid of dot notation in general,

-- that's my Silicon Forest mesage of the day (MOTD).

Paul should like my message as I'm not telling the misbehaving to mess with
his classroom experience. I'm advising them to stay home. No dot
people. We are part of the solution.
