hi nando,
I think there could be application code using the currency() method
(maybe here in RiskMap we use it, I can't remember), so  maybe we
could: 
 * overload the constructor, providing a "currencyless" constructor
   and throw an exception from the currency() method iff currency_ ==
   INVALID_CURRENCY (we could add an INVALID_CURRENCY item to the
   Currency enum, in case it doesn't break other stuff)
 * provide a default currency value (I would'n like it btw).
what do you think?
ciao,
enrico
