Python learned that lesson in moving from python 2 to python 3, so Julia
creates lazy ranges by default. With the focus Julia has on performance,
this would probably an obvious choice anyway.
For the ideom you present, we actually don't even create a range (because
of inlining), but generate equivalent machine code to the similar C code.
for (int i = 1; i <= 10; i++){
#println(i)
}
