I don't think this line needs to change. I feel like it draws attention away from basic identifiers in a way that could be confusing.

Yeah, I thought about this... you definitely have a point. I just wasn't sure if it would be misleading to "go back" on the initial definition of an identifier slightly. But fair enough.

Nit: Comma splice. Trade the last , for a . and replace which with The `r#`

Hmm I think you misread perhaps? It wouldn't make sense like that grammatically.

A raw identifier is like a normal identifier, but prefixed by `r#`. The `r#` is not included as part of the identifier.

I'm not sure that improves clarity, but if you really want, I'll do it. 😉

Actually, looking at it closer, another option is to change ", but" to "except". So A raw identifier is like a normal identifier except prefixed by `r#`, which is not included as part of the identifier. The main thing is to get rid of one of the commas as it's currently grammatically murky with both of them.

"...any strict or reserved keyword" except crate, extern, self, Self or super.

Okay, I thought there might be exceptions, thanks.

The grammar is technically okay as-is, but if it made you misread it, then it could plainly be clearer! I don’t want to confuse others after all. I think I’ll go with your first suggestion if that’s alright. (You still need the comma after “identifier” in your second suggestion.)

Can we get this merged now that the actual Rust feature has been stabilised? :-) |
