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 16:44:21 -06:00			`macro_rules! recursive {`
