[PATCH] D138861: [Clang] Implement CWG2640 Allow more characters in an n-char sequence

Tue Nov 29 10:41:24 PST 2022

aaron.ballman added inline comments.

================
Comment at: clang/test/CXX/drs/dr26xx.cpp:41
+#define a z(
+int x = a\N{abc}); // expected-error 2{{'abc' is not a valid Unicode character name}}
+
----------------
Why do we get two errors here?

Also, can you add this case:
```
int y = a\N{LOTUS});
```
to show that we now form an identifier for `a\N{LOTUS}` instead of trying to expand `a` as a macro; we should get a new diagnostic about the stray `)` instead.
