I looked again at some of the examples. It seems to me that if a "value" 
or "amount" class name clearly separates the symbol, if any, from the 
value, then parsing should be fine.

Moreover, it seemed to me that when the dollar symbol or cents symbol is 
used, its meaning may more correctly be viewed as the unit of the 
currency, instead of the symbol of the currency.

For instance, in "¢2.1 USD", the currency is "USD", and the unit is "¢", 
but "¢" is not the symbol of currency "USD".
