Greetings. I have just uploaded Memoize-ExpireLRU-0.54.tar.gz to CPAN. The purpose of the module is to provide an LRU expiration policy for Memoize. The version number started at 0.52 to match memoize, and then got moved up to make the thing work in non-trivial cases. To quote the README file: This is the README file for Memoize::ExpireLRU Memoize::ExpireLRU is a module that implements LRU expiration for Memoize. To build and install this extension, simply chant: perl Makefile.PL make make test make install Memoize::ExpireLRU requires Memoize version 0.52 or greater. The DSLI entry for the module should be: Hash::NoVivify Name DSLI Description Info ------------- ---- -------------------------------------------- ----- Memoize:: ::ExpireLRU Rdpr Provide LRU Expiration for Memoize BPOWERS A readme is included, as well as a standard perl build environment (Makefile.PL, MANIFEST, t/*, et al) Cheers.
