    Make a TreeMaker that will result in an extractor call specified by extractor the next TreeMaker (here, we don't know which it'll be) is chained after this one by flatMap'ing a function with binder nextBinder over our extractor's result the function's body is determined by the next TreeMaker in this function's body, and all the subsequent ones, references to the symbols in from will be replaced by the corresponding tree in to
