The current situation is that private non-static functions are callable from XS modules on all platforms *except Windows*. I have submitted a PR that makes them non-callable on almost all the other platfroms: https://github.com/Perl/perl5/pull/19655 It's a pretty major change and that PR hasn't received much attention, so I'm making this post to get your opinions. This change will likely cause some CPAN breakage. I imagine there will be three kinds of breakages: 1. Modules that call functions that shouldn't have been marked as private. 2. Modules that call private functions for no reason and can be easily patched to use public functions instead. 3. Modules that call private functions to accomplish something that can't be done with public APIs 1 & 2 are easily fixable. Number three may require us to either design new APIs or just expose the needed private APIs and call it a day. On #p5p, randir has expressed a concern that the breakage may be unacceptable. My opinion is that we're very early in the release cycle and we have plenty of time to deal with the potential fallout. Also, it can't be *that* big considering that most of CPAN works on Windows just fine. What does p5p think?Thread Next
