See repo

Problem: RA reports an error of the macro, but the code compiles just fine on the command line.

What error do you get, "missing ,"?

[Diggsey]

I've started getting an error, "expected ," on format! macros too...

[lnicola]

#17463, but it seems unlikely to affect format!.

[wackazong]

I get "expected `,`" as well

I've triggered a new nightly release, you can try it in about 15 minutes. But I suspect it's going to fix this issue.

New release is out, you can get it from GitHub or the VS Code Marketplace.

Ok, works for me. Thanks. I will leave the issue open for @Diggsey to confirm.
