"Only the OP can decide what comes next."

Based on a huge performance difference with C, I think I'll make an XS clone of Algorithm::LUHN so this is more generally useful for others. It introduces some requirements that will slow things down (like this, but it seems to be the most popular module with LUHN10 in it.

Appreciate all the help from everyone. If I do get get it done, I'll reference/credit all in the module.
