TODO: - [ ] test writing of .nif files - [x] implement loading of fields in PType/PSym that might not have been loaded - [ ] implement interface logic - [ ] implement pragma "replays" - [ ] implement special logic for `converter` - [ ] implement special logic for `method` - [ ] test the logic holds up for `export` - [ ] implement logic to free the memory of PSym/PType if memory pressure is high - [ ] implement logic to close memory mapped files if too many are open. --------- Co-authored-by: demotomohiro <gpuppur@gmail.com> Co-authored-by: ringabout <43030857+ringabout@users.noreply.github.com> Co-authored-by: Jacek Sieka <arnetheduck@gmail.com>
