Having a consistent ("regular", in the linguistic sense), structure
for something like the op= form is obviously very desirable. It's so
much easier to teach and learn a rule like "op= has the same effect,
whatever "op" is; it takes the variable on the LHS, applies the
operator to its contents and
P.S. My apologies for top-posting in the quoted text, and my apologies
to William for the duplication.

A zen-slice only affects the single reference it's applied to.
And it is a no op when applied to anything other than a `Scalar`.
