The :data:`types.FunctionType` constructor now inherits the current builtins
|

if the *globals* dictionary has no ``"__builtins__"`` key, rather than using

``{"None": None}`` as builtins: same behavior as :func:`eval` and

|
:func:`exec` functions. Defining a function with ``def function(...): ...``
|
|
in Python is not affected, globals cannot be overridden with this syntax: it
|

also inherits the current builtins. Patch by Victor Stinner.

:mod:`readline`: Explicitly disable bracketed paste in the interactive
|
|
interpreter, even if it's set in the inputrc, is enabled by default (eg GNU
|
|
Readline 8.1), or a user calls ``readline.read_init_file()``. The Python
|
|
REPL has not implemented bracketed paste support. Also, bracketed mode
|
|
writes the ``"\x1b[?2004h"`` escape sequence into stdout which causes test
|
|
failures in applications that don't support it. It can still be explicitly
|
|
enabled by calling ``readline.parse_and_bind("set enable-bracketed-paste
|
|
on")``. Patch by Dustin Rodrigues.
