Looking in the documentation for inspect.getcallargs (https://docs.python.org/3/library/inspect.html#inspect.getcallargs), it appears that inspect.getcallargs is deprecated in favor of inspect.Signature.bind and inspect.Signature.bind_partial.

However, when I use inspect.getcallargs, I do not get a DeprecationWarning, while I do get one for other methods that have been deprecated in the inspect library.

Because a warning is not issued when inspect.getcallargs is used, it confuses me as to whether this method is actually deprecated or not, since there seems to be a lot of discussion in previous issues about whether this method should be deprecated or not. If it is truly deprecated, should a DeprecationWarning be added?

For my situation, I would prefer to use inspect.getcallargs due to its more descriptive error messages when incorrect arguments are used, but if it truly is deprecated, then I should use inspect.Signature.bind instead.

There was some discussion over undeprecating getcallargs at https://bugs.python.org/issue27172#msg281825 that there are some behavior changes with signature.bind

As far as I can see from https://bugs.python.org/issue20438 this deprecation is meant to be a documentation level deprecation discouraging usage than a code level deprecation adding a DeprecationWarning to be removed later. I might be wrong here. I am adding Yury for clarification.

Thanks

Submitted PR to add the deprecation warning, since this initial discussion, some other functions also raise DeprecationWarning's in code.
