Lisp's dead, baby. Lisp's dead.

Can I have his motorcycle?

Lisp codewalking requires using compiler-specific implementation-dependent codewalkers to be robust.

Yeah, just use macrolet.

I suddenly felt very sad while reading the linked post.

I don't understand the problem. What do they mean by code walking?

I should have read the whole thing before responding. To implement that well you need a framework that allows macros to be aware of each other when they should interact. When it walks the interior code it could look for handlers in a table. When defining new macros, add appropriate handlers to the table.

Sometimes you can't escape complexity. But at least writing that macro in lisp is possible.
