What if plain-equals and value-equals are independently overridable,
with defaults:
   boolean equals(any x) { return (x instanceof ThisClass) && equalValue(x); }
   boolean equalValue(ThisClass x) { ... check bit equality ... }

(The equalValue method could be named "equals" too, but doing so
is too confusing for now.)
Where operator== calls equalValue, not plain equals.

The effects cascade to many of the Collection methods.
