The unary "negate" operation and the binary "subtract" operation are usually distinguished by context, i.e. by whether prefix or infix notation is used. Unless you do some tricks (like calling one "sub"), the above would likely be parsed as an attempt to call "negate" with two arguments, which is a syntax error. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
