That is excellent advice.

So:
config = configparser.ConfigParser()
try
call_tracing()| enables explicit recursion of the
tracing function.
Is there any reason it doesn't support
sys.call_tracing(/func/, /args/, kargs)
to call
func(*args, **kargs)
?

Is it too difficult?
Would it slow down the compiler too much?
Question 2:
Couldn't this be done (or is it to some extent already done) with
other-built-in types, e.g. couldn't
[1] + [2] be compiled as [1,2]

This idea was partly inspired by Michael Stemper asking about best
practice for placing, and finding, a configuration file.
Thoughts?

contains a list of directories separated by semicolons and which you can
access as os.environ['PATH'] .

This is not my area of expertise, but there is a misplaced quote before
'__init__'
that should be after
'Flags3
Correct this, and your example runs without error.

It would be more natural

I don't have a strong opinion on this; there may be good reasons for
preferring one to another.
Does anybody think this is a good idea?

__exit_context__.value would be the return value
isinstance(__exit_context__, ReturnContext)
be True and when would it be False? What would __exit_context__.value
be? I can't think of a sensible meaning for it. If no exception occurs,
is the value returned by f supposed to be 10/x or __exit_context__.value
