...prompt.

A problem with the GNU Readline package may prevent this.

...interpreter.

I'd prefer to use different fonts to distinguish input from output, but the amount of LaTeX hacking that would require is currently beyond my ability.

...value.

Actually, call by object reference would be a better description, since if a mutable object is passed, the caller will see any changes the callee makes to it (e.g., items inserted into a list).

...etc.

The rules for comparing objects of different types should not be relied upon; they may change in a future version of the language.

...somewhere.

In fact function definitions are also `statements' that are `executed'; the execution enters the function name in the module's global symbol table.

...space!

Except for one thing. Module objects have a secret read-only attribute called __dict__ which returns the dictionary used to implement the module's name space; the name __dict__ is an attribute but not a global name. Obviously, using this violates the abstraction of name space implementation, and should be restricted to things like post-mortem debuggers...
