Knee-jerk? There's nothing pretty about having every single semantic of your language need to wrap. That's called, syntax hell. And it's useful for when you want to refer the AST self-referentially, like in live editors, ie. emacs & overtone (music production.) Otherwise, it's water trash. Maybe it was cool in the 80s when the only other kid on the block was Fortran or QBasic - but we have better languages now, so we don't need to write our program as a big nested list..we can make it easier for ourselves, and we can be way more productive..well unless..we're some old dude from the 80s..that's stuck on the LISP bandwagon. tears
