# 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"]
