if that is true - it's quite an important observation:


   def alot_faster
     <snip 10000 lines>
   end


   def not_so_fast
     not_so_fast_0
     not_so_fast_1
     not_so_fast_2
     not_so_fast_3
   end
   def not_so_fast_0
     <snip 2500 lines>
   end
   def not_so_fast_1
     <snip 2500 lines>
   end
   def not_so_fast_2
     <snip 2500 lines>
   end
   def not_so_fast_3
     <snip 2500 lines>
   end

always true - but perhaps in ruby __particularly__ true.  an argument for a
preprocessor?
