Hot take: software documentation focused on code tutorials will become obsolete. In AI-first development, documentation should teach humans the ideas behind a piece of software, while agent skills take care of code related details. I need to start doing my part on Sane C++ docs

An example of "struct dumping" in Sane C++ Libraries. Anything SC::Segment based (Vector / String / VectorMap etc.) can be dumped and restored by just casting it (well, start_lifetime_as 🤭). I guess it's not rocket science but recent additions make creating this simple and easy. #cpp #cplusplus

While debugging some of the recent container issues for Sane C++ Libraries I have been starting to track the number of allocation and deallocations calls. The test suite by itself is doing 20K allocations and ~50K re-allocations 🫠. Is it MAYBE time to add support for custom allocators? 😅

It looks like self-relative pointers in C++ always cause UB, unless done through member ptrs. Member ptrs don't seem to be usable as generalized self-relative ptrs, to locate the start of a dynamic array memory inside an arena or something similar... Time to rollback the relative pointers change?🙄
