Try a "back-to-basics" approach of writing less structured code, as in, factor it less, use more plain data structures, just write straight-line imperative blocks of code. This is actually the path of least resistance in most languages, but they all offer shiny features and don't stop you from overcomplicating it by prematurely distributing functionality into abstractions.
