- (macro-rules sym ... (keyword ...) (pat (where . fenders) .. tpl) ....)syntax
like syntax-rules, but the templates are usually quasiquote-expressions. Moreover, the symbols sym ... are injected, if there are any.
Note, that non-symbol literals are accepted in each pat and considered a match if they are equal to a corresponding literal in the macro-code.
macro-rules must be imported for-syntax.
