Lisp and similar are just "hey it's really easy to write a parser if we just make all programmers write the AST directly!". Cool if the goal of your language is a really simple parser. Not so cool if you want to make it pleasant to read for humans.
That's my impression, at least. Like I said, I've never actually used a Lisp. Maybe I'm put off by the smug superiority of so many Lisp people who presume that using Lisp makes them better at programming, smarter, and probably morally superior to me.
