I certainly agree that it would add some balance, perhaps even elegance, to
Euphoria if you could specify a "list" of targets which accept a function
return.  However, the idea that a function can only return one value is
misleading. I routinely wriite functions which return anywhere from 2 to 100 or
more "values". e.g. pass the function "age_account" a sequence containing
a customer record (name, address.... 30,60,90 day balances, current
transactions) and return an  updated record with balances adjusted.
