Nadrieril	a2dcb3a6d9	Disallow an arm without a body (except for never patterns) ... Parsing now accepts a match arm without a body, so we must make sure to only accept that if the pattern is a never pattern.	2023-12-03 12:25:46 +01:00
Nadrieril	0bfebc6105	Detect attempts to expand a macro to a match arm again ... Because a macro invocation can expand to a never pattern, we can't rule out a `arm!(),` arm at parse time. Instead we detect that case at expansion time, if the macro tries to output a pattern followed by `=>`.	2023-12-03 12:25:46 +01:00
