Gavin! I took a look at Numeric#format_s. I'm thinking this function
is doing too much. Wouldn't it be better to separate the setup of the
"locale" from the actual formatting of the "Money"? Because the setup
is something you probably do once, but you may want to output many,
many moonies. This probably means that this can't be a member of
"Numeric" any longer. Rather the format function has to be a member of
a separate "NumericFormat"-class (initialized with the proper
"locale"). what do you think?
