The = sign doesn't guarantee unreserved symmetry between expressions.

NOTHING creates symmetry between EXPRESSIONS.
It is THE SIGN that has symmetry. It is = ITSELF that *is*
symmetric.

I can be a reminder or sign that is appended to one expression to show
that that expression is referencing another expression.

It CAN'T avoid being PREpended to the "another" expression in THAT
context.
And whether you append or prepend fundamentally makes NO difference --
there
is no law requiring left (as opposed to right) to be "pre" or "first";
indeed a great
many languages OTHER than English do in fact do it the other way.


1) Taking the expression sq.rt4 = 2. Sq.rt4 refers to 2. 2 does not
refer to anything. 2 is the object itself. It is presented, we don't
need to refer to it, it is there in front of us to use as we wish.

Since one of the uses we could wish is to remind people that it is
the
positive square root of 4, we CAN ALSO SAY 2=sqrt(4). THAT is because
*=* is symmetric. This has nothing to do with any preferred roles of
things
on the right as opposed to the left.

2) A = A (or A is equal to itself) is another asymmetric use of the = sign.

This article you just posted is another assholic use of public
stupidity.

An object that references itself is not the object referenced by
another.

But it STILL IS the object referenced by ITSELF, which, SYMMETRY being
what
we're talking about here, IS a CONFIRMING example of symmetry.

Object properties are given by reference,

No, they're not. You can refer to a thing without giving ANY of its
properties
other than the route by which it is referenced.

but not by self-reference.

In order to perceive the reference, you would have to HAVE ALREADY
BEEN
given SOME reference to the object. Whether that reference is or
isn't self is something
you may OR MAY NOT be aware of. You have to EVALUATE the
reference. You have
to FOLLOW the reference.

The real asymmetry you are looking for involves evaluation, involves
getting closer
to some simpler or "normal" form. You need to google (or wiki) the
phrase
"rewrite rules". Believe it or not, for all your pretensions to
knowing enough to be
able to educate us (and they truly are pretense), YOU ARE NOT THE
FIRST person
to notice that = can be asymmetric. You are, perhaps, however, the
most incompetent.
