This is a very interesting discussion. I especially like the mathematical explanation by @cjdoris considering it as group action. For me the main concern seems to be that the group action is just denoted by an integer. For instance, in the example

```julia
Date(2022, 3, 16) + Day(1)

```

it is clear that Day(1) denotes a time interval/shift. In this interpretation

```julia
'a' + 1

```

should be understood and maybe explicitly written as

```julia
'a' + NextCharacterInTermsOfUnicodeCodepoints(1)

```

being open to suggestions for any other shorter, yet descriptive type 😉
