<pre>
    According to §5.10 Identifiers [lex.name], "Unless otherwise specified, any ambiguity as to whether a given identifier has a special meaning is resolved to interpret the token as a regular identifier."

Does this mean that clang is incorrect to emit an error in this case?

```
$ cat ~/tmp/module_ident.cpp 

using module = int;
module i;
int foo() {
    return i;
}
```

```
$ clang++ -c ~/tmp/module_ident.cpp -std=c++20
