Would this be better for rev step by 2

[ghmorrison]

I am still just learning Rust but I liked the second one better.

Section: Combining Iterator Adaptors
Sub-section: Complex Chains

for i in (0..=10).rev().filter(|x| x % 2 == 0) { print!("{} ", i); }

for i in (0..=10).rev().step_by(2) { print!("{} ", i); }

Again for:

`let r = (1..20)
.filter(|&x| x % 5 == 0)
.chain((6..9).rev());

for i in r {
print!("{} ", i);
}`

`let r = (5..20)
.step_by(5)
.chain((6..9).rev());

for i in r {
print!("{} ", i);
}`

Thanks for the tutorial,
George
