Description: PEP 593 has been accepted some time ago. I got a green light for merging this from Till, so I went ahead and combined the code contributed to typing_extensions[1] and the documentation from the PEP 593 text[2]. My changes were limited to: removing code designed for typing_extensions to run on older Python versions removing some irrelevant parts of the PEP text when copying it over as documentation and otherwise changing few small bits to better serve the purpose changing the get_type_hints signature to match reality (parameter names) I wasn't entirely sure how to go about crediting the authors but I used my best judgment, let me know if something needs changing in this regard.
