You could use '*' and '+', if you always know
when you're dealing with a 3-valued boolean
(troolean? trillian?).

By the way, I think Python 2.0 should let you define
new infix operators -- and design new characters to
represent them! We all have bitmapped screens now --
there's no reason why we should be restricted to a
fixed character set any more...
