[ Curaçao: Since the language permits "struct", the LWG views this as NAD. They suggest, however, that the Project Editor might wish to make the change as editorial. ]

Proposed resolution:

Change the synopsis to reflect the useage in [negators]

[ Taken from comp.std.c++ ]

In [function.objects] the header <functional> synopsis declares the unary_negate and binary_negate function objects as struct. However in [negators] the unary_negate and binary_negate function objects are defined as class. Given the context, they are not "basic function objects" like negate, so this is either a typo or an editorial oversight.
