I was following this discussion closely. I must say that I kind of like
your class. Especially in the way you propose it - as a convenience
wrapper build on top of algorithms. Having both, we have win-win scenario.

Just one remark on top of mutable vs. copy.

As you said, the major reason for coming with this class was a clarity
of code. I must say, that when I read s.trim(), I pretty much assume,
that the operation is performed on 's'. So mutable is natural winner for
me here.
