Eric Snow a450a0ddec gh-135443: Sometimes Fall Back to __main__.__dict__ For Globals (gh-135491)
For several builtin functions, we now fall back to __main__.__dict__ for the globals
when there is no current frame and _PyInterpreterState_IsRunningMain() returns
true.  This allows those functions to be run with Interpreter.call().

The affected builtins:

* exec()
* eval()
* globals()
* locals()
* vars()
* dir()

We take a similar approach with "stateless" functions, which don't use any
global variables.

The Python C API
================

The C API is divided into these sections:

1. ``Include/``: Limited API
2. ``Include/cpython/``: CPython implementation details
3. ``Include/cpython/``, names with the ``PyUnstable_`` prefix: API that can
   change between minor releases
4. ``Include/internal/``, and any name with ``_`` prefix: The internal API

Information on changing the C API is available `in the developer guide`_
