This I agree is a bit of a bummer, it would be useful for the parsers to 
take CharSequence for flexibility.  Integers aren't hard to parse but 
floats and doubles are non-trivial.

Note however that Scanner accepts both Readable (a Reader) and 
ReadableByteChannel in its constructors.

Probably because Strings needed to be immutable and there's no way to do 
that when sharing a mutable buffer.

Nope, see above.

Probably because they don't want you doing stupid broken things, like 
trying to share buffers between immutable and mutable objects.

I still agree that CharSequence could be made more useful though, that's 
a good idea.  Hmmm.
