Summary: There's my problem, and others. I'm willing to provide a patch, if
supported.
There's a gotcha here. I fell into it. The docs for eval state
===
eval(expression, globals=None, locals=None)
The arguments are a string and optional globals and locals.
===
I read this and concluded, fairly I think, that I'm not allowed to pass in a
code object [1]. So I didn't read any further. I'd already got the answer to my
question.
But I knew that exec would take a code object, so I had doubt, and did my
little experiment.
I'd prefer something more like exec, which says
===
This function supports dynamic execution of Python code. object must be either
a string or a code object.
===
There are other problems, such as not agreeing with the help(eval) etc messages
(and the still open #22057, #25810):
===
eval(source, globals=None, locals=None, /)
Evaluate the given source in the context of globals and locals.
The source may be a string representing a Python expression
or a code object as returned by compile().
The globals must be a dictionary and locals can be any mapping,
defaulting to the current globals and locals.
If only globals is given, locals defaults to it.
===
exec(source, globals=None, locals=None, /)
Execute the given source in the context of globals and locals.
The source may be a string representing one or more Python statements
or a code object as returned by compile().
The globals must be a dictionary and locals can be any mapping,
defaulting to the current globals and locals.
If only globals is given, locals defaults to it.
===
Finally, I'm willing to provide a patch, if supported. (I've not contributed to
Python before.)
[1] I'd just read the docs for exec, which is up-front about 'string or code'.
