Moo is very adept at providing a very lightweight and quick way to provide 'Modern' object oriented interface. While it is true that Moo itself has dependencies, I have observed that they are fairly lightweight.
Sometimes, the lack of certain features in itself is a feature, and I think Moo expresses this very well.
Of course, the lack of features.. is well.. a lack of features. But for what it's worth, I find dealing with Moo's "lack" of features easier than dealing with M[ou]ose's larger featureset.
Also, I personally find Moo's stack traces are easier to read and understand.
