Method chaining can still _be_ magical, and not have to _look_ like magic.
number = 1234567
# Chaining methods more than once-ish is confusing; the developer has to keep
# in mind wtf is going on:
number.to_s.reverse.split(//).each_slice(3).map(&:join).join(',').reverse
# Commenting the state of each chain helps:
number.to_s. # String, e.g. "1234567"
reverse. # reverse it, e.g. "7654321"
split(//). # split on every character, e.g. ["7", "6", "5", "4", "3", "2", "1"]
