I had not seen that. I don't care for it though: Why is $u->u5c0f;, after creating $u, which generates a different method for every character the first time it is used, any better or easier than just writing "\x{5c0f}"? You would only use the literal method name call if you had the character code already as a compile-time literal, so what is the possible point?

It also has $u->name, which seems to be identical to using \N{}.

So why did you mention this module? Are you just mentioning things that show up on a keyword search without seeing what they actually are (which is what it gives the impression of; sorry if that's not the case), or is there something you want to discuss about this approach or the lessons it can teach? If that's the case, please elaborate.
