Actually, I rather blithely skipped over the real point in Alex's question.
Although my code shows how to do coercion via double dispatching in
Ruby, it ignores the domain question of what does it mean to add an
integer to a currency.
$5 + 1 what?
It's not clear that an integers and currency really SHOULD be
compatible in this way.
