Agree, pushed.

But I have a notice about number of arguments. Seems, special values for hash 
and greatest/least functions is not actually needed. If we split nargs option to 
n mandatory arguments and n optional ones then special values for that functions 
will go away: hash will have 1 mandatory and 1 optional, greatest/least will 
have one mandatory and infinite number of optional. Not sure for now about 
CASE/WHEN case. But seems it's a deal for separate refactoring.
