I am of two minds:

1. I like this. You can "poison" operators==/!= to prevent them from
working. It might be worth enshrining this as a Boost.Operators template or
something (including poisoning) so that the idiom can be easily re-used.
Don't tell me it's just syntactic sugar; /everything/ is syntactic sugar;
syntax counts! If it didn't, we'd just write machine code.

2. What a waste of time; this is just syntactic sugar. It doesn't even make
things very sweet, and it comes with associated dangers (op==/!=). Getting
it right is complicated, and complexifies the code.
