docs: add CPAN compatibility reports for Scalar::Util and Memoize#497
Conversation
Detailed investigation of both modules against their CPAN test suites: - Scalar::Util (Scalar-List-Utils 1.70): 606/816 subtests pass (74.3%). All 14 exported functions implemented; isvstring is a stub, tainted always returns false (no taint mode), readonly partial. Most failures are in List::Util/Sub::Util functions. - Memoize 1.17: Core functionality fully working (7/16 test files pass). All failures are peripheral: deep recursion stack overflow, threads not available, DB_File shim bug. Good bundling candidate.

Scalar::Util: - Fix isvstring() to actually check VSTRING type instead of always returning false. The VSTRING type infrastructure was already complete; only the isvstring() function was missing the check. List::Util: - Implement zip, zip_shortest, zip_longest (returns list of arrayrefs) - Implement mesh, mesh_shortest, mesh_longest (returns flat interleaved list) - These 6 functions were declared in @EXPORT_OK but had no Java backend Memoize: - Bundle Memoize 1.17 from perl5/cpan/Memoize/ into the JAR - Add import-perl5 config entries for Memoize.pm and Memoize/ submodules - Pure Perl module, all dependencies already satisfied Plan documents: - Add dev/modules/scalar_util.md with full bug analysis and fix plan - Add dev/modules/memoize.md with dependency analysis and bundling plan Generated with [Devin](https://cli.devin.ai/docs) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>
Add passing CPAN tests to the bundled module test suite: Scalar-List-Utils (13 tests): any-all, blessed, isvstring, max, maxstr, mesh, minstr, prototype, readonly, rt-96343, stack-corruption, sum0, zip Memoize (7 tests): basic, cache, expmod, expmod_t, flush, normalize, unmemoize All 20 tests pass under make test-bundled-modules.
