You can try Text::LevenshteinXS for the need for speed.

You can also try Text::WagnerFischer and Text::Brew to play with operation's weights/costs to detect letters swap.

There are also Text::PhraseDistance that is suited for phrases but that can benefit from a custom distance. The 0.01 version has also a dinamic technique (slow), instead the 0.02 solves the issue for the marriage problem.

    It would be hard to beat Abigail-IIs implementation of comp for performance, and I don't need the full power of Levenshtien for this, but I''l be sure to grab the XS version next time I need it.

    Thanks for the pointers.
