| Subject: | Evaluate List::ByUtils::XS |
On longer lists, it's significantly faster than List::ByUtils, but there are some minor incompatibilities noted in the documentation. It may be worth investigating to see if it could replace List::ByUtils for Lowu. (Or Lowu could detect if it's available, and if not fall back to List::ByUtils.)
On the other hand, PEVANS apparently plans to port List::ByUtils to XS himself; that might result in an XS implementation with fewer incompatibilities.
