dear pythoneers,
i would be very gladly accept any commentaries about what this
sentence, gleaned from
http://celabs.com/python-3.1/reference/executionmodel.html,
is meant to mean, or why gods have decided this is the way to go. i
anticipate this guy named Kay Schluehr will have a say on that, or
maybe even the BDFL will care to pronounce ``__builtins__`` the
correct way to his fallovers, followers, and fellownerds::
The built-in namespace associated with the execution of
a code block is actually found by looking up the name
__builtins__ in its global namespace; this should be a
dictionary or a module (in the latter case the module’s
dictionary is used). By default, when in the __main__
module, __builtins__ is the built-in module builtins;
when in any other module, __builtins__ is an alias for
the dictionary of the builtins module itself.
__builtins__ can be set to a user-created dictionary to
create a weak form of restricted execution.
Short answer: use `import builtins` (spelled __builtin__, no 's' and
double underscores, in Python 2.x) to access the module containing the
predefined (built-in) objects.
Everything else is an implementation detail.
