Description
Given the following code: https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=9adebfa3cae4c99b1fa5c0c9f25e154a
fn main() {
l et x = 5;
}
The current output is:
error: expected one of `!`, `.`, `::`, `;`, `?`, `{`, `}`, or an operator, found `et`
--> src/main.rs:2:7
|
2 | l et x = 5;
| ^^ expected one of 8 possible tokens
Ideally the output should look like:
error: expected one of `!`, `.`, `::`, `;`, `?`, `{`, `}`, or an operator, found `et`
--> src/main.rs:2:7
|
2 | l et x = 5;
| ^^ expected one of 8 possible tokens
hint: did you accidentally put a space inside the keyword `let`?
Sometimes you accidentally insert whitespace inside a keyword, and might not notice it immediately. This minimal case is pretty obvious, but it might not actually always be that obvious if a lot is going on.
This could even be extended to cover all names in scope.

Why did you close this issue? I think it's a good idea.

I don't think there's any value to implement it, since the mistake is always obvious, but I can reopen it if you'd like

I think it's still worthwhile because people can sometimes get confused in the moment, especially if macros are involved.
