    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 (furthermore, the interpretation of flatMap depends on the codegen instance we're using).
