This reminds me how you can save a bunch of bytes just by making sure your structs are aligned. In go for example:

  type Wasteful struct {
    a int16
    b int
    c byte
  }

  type Aligned struct {
    b int
    a int16
    c byte
  }

Will have sizes of 24bytes and 16bytes (on a 64bit system). Same data 8bytes more. If you are storing millions of those objects, then it adds up.
