The proposal doesn't address arithmetic progressions, geometric 
progressions, or any other type of sequence: just intervals of 
consecutive integers.

But if you expanded your example a little:

for (int l = 0; l < 10; l += 2)
   do smth(l)

you would see that it is easy to handle it with the proposed new syntax:

for 0 <= h < 5:
    do smth(2*h)
