Modernize macro_rules! invocations macro_rules! is like an item that defines a macro. Other items don't have a trailing semicolon, or use a paren-delimited body. If there's an argument for matching the invocation syntax, e.g. parentheses for an expr macro, then I think that applies more strongly to the inner delimiters on the LHS, wrapping the individual argument patterns. 2015-01-02 22:44:21 +00:00			`macro_rules! e {`

parser: Do not call `bump` recursively Token normalization is merged directly into `bump`. Special "unknown macro variable" diagnostic for unexpected `$`s is removed as preventing legal code from compiling. 2020-02-16 13:47:24 +00:00			//~^ ERROR expected expression, found `$`
