I created the issue #19518 to add documentation (but also to add even
more functions :-)).

As most PyRun_xxx() functions, the function is declared in a "#ifndef
Py_LIMITED_API" block. It means that it is not part of the stable ABI,
is that correct?

Yeah, it would be nice to have a tool to list changes on the stable ABI :-)

For a previous issue, I also added various other functions like
PyParser_ASTFromStringObject() or PyParser_ASTFromFileObject(). As
PyRun_InteractiveOneObject(), they are declared in a "#ifndef
Py_LIMITED_API" block in pythonrun.h. These new functions are not
documented, because PyParser_AST*() functions are not documented.


The patch parser_unicode.patch was attached to the issue during 2
years. First I didn't want to commit it becaues it added too many new
functions. But I pushed by change because some Windows users like
using the full Unicode range in the name of their scripts and modules!

If it's not too late, I would appreciate a review of the stable ABI of
this changeset.
