HN comment order

A good question for any "macro" systems like this is something like the following: 1. Suppose you've written a function 'foo' in your language that does something useful (e.g.: partitions a sequence, validates a map, or pretty much anything really). 2. Some time later you want to write a macro 'bar'. 3. Can you use function 'foo' when writing 'bar'? If the answer to 3 is "no" then you don't really have Lisp-like macros. This is what makes Lisp macros…

> Why? Because a language without macros is a tool: You write applications with it. A language with macros is building material: You shape it and grow it into your application. Very nice! If only this could work with C++.

That's me! I was really naive about parsing back then and the "parser" is really not stellar.
