[FRIAM] What is an object?

[Russell Standish]

Not sure about "utility"/"tool", but an object is distinguished from a
function by having state. Call an object's method, and the method's
scope is populated by the object's data members, which of course,
differ from object to object.

By contrast a function either has no state (pure function), or its
state is global (same for every function invocation).
