I think you understand the map implementation, but what you're missing
is that I can't just return a System.String from String.subSequence,
because the calling code expects an interface CharSequence. I can't just
substitute a string for that because the same code might also want work
with other classes that implement CharSequence.

BTW, it would be possible for me to implement String.subSequence, by
returning an instance of my own helper class that implements
CharSequence, but since this is only a partial (and probably useless)
solution, I chose not to do that.
