Hrmmm, while your approach has merit, it doesn't really address the dogma that surrounds the more general issue of usage of temporary files in Perl - The movement of application temporary file generation into (presumably) owner-only writable directories makes a number of assumptions about the application platform:
- The platform supports multiple users and path expansion of the tilde into home user directories,
- The platform honours sticky-directory permissions so that the created temporary file remains accessible with permissions of the users home directory
Additionally, the use of function library calls for common tasks such as temporary file creation and utilisation offer greater cross-platform portability for applications with the differences in platform structure implemented within the library rather than the application code.
