    Perform a recursive rewrite.

    Perform a recursive rewrite. The following pattern is pretty common throughout Mimir: def replaceFooWithBar(e:Expression): Expression = e match { case Foo(a, b, c, ...) => Bar(a, b, c, ...) case _ => e.recur(replaceFooWithBar(_)) } Note how specific rewrites are applied to specific patterns in the tree, and recur is used to ignore/descend through every other class of object
