While iter is a built-in function, it would be clearer if you
referenced the __builtins__ namespace. Built-in objects are linked
into the interpreter, either statically or from a shared library (.so,
.pyd). But the __builtins__ namespace can and does include names for
non-built-in objects (e.g. help and exit). The important point in this
context is that iter is in the builtins module, not that it's a
built-in function. There are lots of built-in objects that aren't in
builtins.
