You don't have to program directly in an AST to do metaprogramming. It's a trade-off: some people feel it's important to make metaprogramming as easy as possible, while others feel it's more important to have readable syntax.

Every Lisp dialect has some high-level syntax, e.g. quote, CL reader macros, and Arc ssyntax. These obscure the relationship between code and the underlying AST, but the designers felt that the gain in readability was worth it.

How much syntax should there be? A hard question, but I think it would be good for Lisp to move in the "more" direction. Readability is one of the big problems I have with Lisp, and macros, while certainly useful, make up only a small fraction of my code.
