"To put forward as fact" seems like the opposite of "to contradict" to 
me. One says, "it's true!" The other, "it's false!"

The only other term that I have found that is acceptable for the unary 
plus operator is "unary_plus." That just seems so ... boring. ;-) And a 
little strange to have "negate" and "unary_plus". Blech.

Is there a mathematician who can tell me if the operation performed by 
the unary plus operator has a name?
