I had read the Fine Manual, but I'm a little dense and don't see the 
relationship between the cited tuple relational operators and bind. ;-)

Re-RTFM, I don't see any other mention of relational operators existing 
or not in regards to FUNTION OBJECT BINDERS. IIRC, Peter added the &&, 
|| operators in may.
