[New-bugs-announce] [issue32222] pygettext doesn't extract docstrings for functions with type annotated params

[Toby Harradine]

New submission from Toby Harradine <tobyharradine at gmail.com>:

### Expected Behaviour
When running pygettext with the -D CLI flag, all module, class, method and function docstrings should be extracted and outputted to the .pot file.

### Actual Behaviour
In the case of functions whose parameters have PEP 484 type annotations, their docstrings are not being extracted. I have attached two files, one .py file and its corresponding .pot file, as examples of this behaviour.
