edit: wish accept these answers. great info everyone!

it's long list. boil down 

aggregate all<tsource> average contains count elementat<tsource> elementatordefault<tsource> empty<tresult> first firstordefault last lastordefault longcount max min sequenceequal single singleordefault sum toarray<tsource> todictionary tolist<tsource> tolookup

the rest either deferred streaming execution or deferred non-streaming execution.
