v1 = [ x  x < [1,2,3,4,5,6]] 
   
v1 is [1,2,3,4,5,6] 
v2 = [ x  x < [1..6]] 
   
v2 is [1,2,3,4,5,6] 
v3 = [ x+y  x < [1..10]  y < [2,4..16]] 
   
v3 is [3,6,9,12,15,18,21,24] (list elements add) 
v4 = [ x+y  x < [2..4], y < [1..2]] 
   
v4 is [3,4,4,5,5,6] (add all pairs of x and y) 
v5 = 1 : [ x+1  x < v5] 
   
v5 is [1,2,3,4...] (starts with 1, next element increments...) 
v6 = [ x+1  x < v6] 
   
v6 goes crazy 
v7 = [1]++[ x+1  x < v7] 
   
v7 is [1,2,3,4...] (same as v5) 
v8 = z where z = 1 : [ x+1  x < z] 
   
v8 is [1,2,3,4...] (use of where) 
v9 = [ (x,y)  x < [1,2,3], y < [2,4,6]] 
   
v9 is [(1,2),(1,4),(1,6),(2,2),(2,4),(2,6),(3,2),(3,4),(3,6)] 
v10 = [ x  x < [1..10], odd x] 
   
v10 is [1,3,5,7,9] (filtering)
