I've never been able to remember where the keys are kept; I'm sure they
keep being moved by previous drivers.

Indeed, in the past I used the term “value” as synonymous (in Python
context) with the term “object”. I have become convinced through this
discussion that I should no longer use the terms that way.

Instead, an object *has* a value at a point in time; if the object's
value can change, we say the object is mutable.

The syntax for literals describe a value, but the object once created
may change its value.

Typically, ‘is’ compares object identity; ‘==’ compares object value.

The concepts are distinct, so I apologise for misleadingly conflating
them in my terminology.
