Matthias Krüger 42ab090be9 Rollup merge of #124488 - est31:arbitrary_expressions_error, r=pnkfelix ... Add a note to the ArbitraryExpressionInPattern error The current "arbitrary expressions aren't allowed in patterns" error is confusing, as it fires for code where it *looks* like a pattern but the compiler still treats it as an expression. That this is due to the `:expr` fragment specifier forcing the expression-ness property on the code. In the test suite, the "arbitrary expressions aren't allowed in patterns" error can only be found in combination with macro_rules macros that force expression-ness of their content, namely via `:expr` metavariables. I also can't come up with cases where there would be an expression instead of a pattern, so I think it's always coming from an `:expr`. In order to make the error less confusing, this adds a note explaining the weird `:expr` fragment behaviour. Fixes #99380		2024-04-29 22:37:51 +02:00
