Looks good!

BTW, you don't have to open an issue for every PR like this one. Just a PR is fine.

Sorry it's just an habit at work and other project. Basically it helps me finding a proper name for the branch :-)

What do you think about adding a test case that shows that the mutator works correctly when the $delimiter parameter is present?

For reference, see http://php.net/manual/en/function.ucwords.php.
