Well, if the purpose of this task is to determine what can be used as an identifier then in F# anything so long as you enclose it in double backticks so: |
|||
<lang fsharp> |
|||
let ``+`` = 5 |
|||
printfn "%d" ``+`` |
|||
</lang> |
|||
{{out}} |
|||
<pre> |
|||
5 |
|||
</pre> |
|||
Is this idiotmatically determined? |

Go allows the underscore, letters, and digits, with "letters" and "digits" defined by Unicode. The first character must be the underscore or a letter. To be exported, the first character must be an upper case letter, again as defined by Unicode. |
