-Builtin-Shadowing
-+++++++++++++++++
-
-Usually the calling of builtins in Python requires two dictionary lookups:
first
-to see whether the current global dictionary contains an object with the same
-name, then a lookup in the ``__builtin__`` dictionary. This is somehow
-circumvented by storing an often used builtin into a local variable to get
-the fast local lookup (which is a rather strange and ugly hack).
-
-The same problem is solved in a different way by "wary" dictionaries. They are
-another dictionary representation used together with multidicts. This
-representation is used only for module dictionaries. The representation checks
on
-every setitem whether the key that is used is the name of a builtin. If this is
-the case, the dictionary is marked as shadowing that particular builtin.
-
-To identify calls to builtins easily, a new bytecode (``CALL_LIKELY_BUILTIN``)
-is introduced. Whenever it is executed, the globals dictionary is checked
-to see whether it masks the builtin (which is possible without a dictionary
-lookup). Then the ``__builtin__`` dict is checked in the same way,
-to see whether somebody replaced the real builtin with something else. In the
-common case, the program didn't do any of these; the proper builtin can then
-be called without using any dictionary lookup at all.
-
-You can enable this feature with the
-:config:`objspace.opcodes.CALL_LIKELY_BUILTIN` option.

-.. _`call likely builtin`:
-
-CALL_LIKELY_BUILTIN
-+++++++++++++++++++
-
-A often heard "tip" for speeding up Python programs is to give an often used
-builtin a local name, since local lookups are faster than lookups of builtins,
-which involve doing two dictionary lookups: one in the globals dictionary and
-one in the the builtins dictionary. PyPy approaches this problem at the
-implementation level, with the introduction of the new ``CALL_LIKELY_BUILTIN``
-bytecode. This bytecode is produced by the compiler for a call whose target is
-the name of a builtin. Since such a syntactic construct is very often actually
-invoking the expected builtin at run-time, this information can be used to make
-the call to the builtin directly, without going through any dictionary lookup.
-
-However, it can occur that the name is shadowed by a global name from the
-current module. To catch this case, a special dictionary implementation for
-multidicts is introduced, which is used for the dictionaries of modules. This
-implementation keeps track which builtin name is shadowed by it. The
-``CALL_LIKELY_BUILTIN`` bytecode asks the dictionary whether it is shadowing
the
-builtin that is about to be called and asks the dictionary of ``__builtin__``
-whether the original builtin was changed. These two checks are cheaper than
-full lookups. In the common case, neither of these cases is true, so the
-builtin can be directly invoked.
-
-You can enable this feature with the
-:config:`objspace.opcodes.CALL_LIKELY_BUILTIN` option.
