This is a driving force behind the pedagogy of SICP -- to think in recursive functions. If you can break down your task into sub-problems and describe them clearly you just have to put a few parenthesis around it. Programming isn't so much about the "code" or syntax; it's semantics and intent aligned with the machine. If you can express your problem clearly then the program practically writes itself.
