I don't agree that parsing is the hardest aspect in all of compilerdom. More like parsing is the least interesting part of what makes a compiler. Perhaps as you allude to, use Lisp or S-expressions as the frontend language and then build the compiler as you don't need much of a parser. Then you can get straight to the more interesting bits.
