Hi all, I have updated the RFC and PR to add the `strict_namespace=1` directive as a way of solving for the global-fallback shadow-function case.
I have also added some research on how prevalent that case actually is; it turns out to be extremely rare among the top 1000 Packagist packages: > In the end, it looks like there are only 2 packages and 8 call sites that > would behave unexpectedly if they converted to function autoloading and > dropped their include calls. Either a use function import or > declare(strict_namespace=1) would fix each one. I have not yet added the "motivation" section, as indicated by earlier comments, but still plan on doing so. Please review again as convenient! -- pmj
