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 14:44:21 -08:00			`macro_rules! bad_macro {`

Mass rename uint/int to usize/isize Now that support has been removed, all lingering use cases are renamed. 2015-03-25 17:06:52 -07:00			`fn takes_x(_x : isize) {`
