love.filesystem.mkdir is a good name because it's very obvious to people who know what "mkdir" means. When I first saw it, I'm sure I knew exactly what it did, and you, whoever is reading this, probably did too.
However, I'd say there are many people out there who don't know what "mkdir" mean, and for them this name could be confusing.
It's also unpronounceable (well, I'm sure we have our own pronunciations of it. :D), seems to not fit in with the general naming aesthetic IMO, and also it doesn't really have anything to do with the command line program mkdir, other than what it does.
love.filesystem.enumerate is also a bit of a puzzling name. Having to guess what this function does if I had never used it or read about it, I would have no idea.
So I was thinking... maybe...
love.filesystem.getDirectoryItems? I know these names are longer... but maybe their obviousness is worth it?
