Interestingly, and as Robert may recall, Jean Ichbiah once proposed that Ada
allow the international currency symbol as a unary operator symbol that was
available for users to overload. JDI's idea was that it could serve as a
lightweight notation for type conversions for user-defined types (typically
unary "+" is used for that purpose). For various reasons his proposal was
not accepted, which is probably a good thing given Robert's news that this
symbol is being evicted from Latin-1 to make room for the euro.
