And there are other non-method sources of arrays:

def mkary
   return 1,2,3
end

GC.start
p ObjectSpace.each_object(Array){}

a = mkary
p ObjectSpace.each_object(Array){}
b = mkary
p ObjectSpace.each_object(Array){}

def mkary2(*args)
   args
end

c = mkary2 4,5,6
p ObjectSpace.each_object(Array){}
d = mkary2 7,8,9
p ObjectSpace.each_object(Array){}

GC.start
p ObjectSpace.each_object(Array){}
