Lisp doesn't really have (much) syntax. The programmer is directly creating a collection of syntax trees (more or less) -- i.e., what most compilers generate after their syntax analysis pass. In fact, you can use Lisp syntax for abstract syntax trees (AST's) as the the output of a parser. Of course it is this very fact that makes code and data interchangeable in Lisp and allows for constructs that other programming languages with syntax can't mimic (e.g., powerful macro features).
