Hello John,

Good point. I started realize that this method
pushes the responsilibty for error handling up the chain,
which is something I sometimes struggle with
with if/else.

Once I really start writing some code, I'll be able
to see the benefits, as I'm sure I'll be happy with
these technique as well.
