Actually, given that "skyline of" is *only* for aggregate sorting (as far as I 
can tell) it doesn't present the complications which QBE did for using a 
function interface.   

Ranbeer, would it be possible to use an aggregate function syntax instead of 
the SKYLINE OF syntax extension?   This allows us to sidestep the issue of 
non-standard additions to the reserved word list.
