Sorry, I did not quite get what you mean.<p>Of course macro+syntax extension got absolutely nothing to do with what you can achieve in a language without macros.<p>And, no, you did not understand. Any custom syntax you&#x27;re adding (if the right tools are used, like mine, for example) would automatically become available for your IDE and all the other tools, because they&#x27;re reusing the same compiler front-end.
