Paredit with Lisp is really slick for moving stuff (including yourself) around the AST. What you're describing, the auto-matching, is really just the tip of the iceberg. With Paredit, there are key chords for moving up, down, and sideways (forwards and backwards) on the tree of Sexps, for transposing two sibling Sexps, for grabbing a sibling (before or after) of a Sexp and making it a child ("slurping"), for taking a child of Sexp and making at a sibling ("barfing"). I have not found a reliable way to slurp statements into the scope of an if statement (Paredit kind of works but tends to misplace semicolons and various other things).
