  // in the Closure code printer. Notably optimizations break typed
  // syntax for arrow functions, by removing the surrounding parens
  // emitting `foo(x:string => x)`, which is invalid.

  // Compiler passes must be disabled to disable down-transpilation to ES5.
  options.skipAllCompilerPasses();

  // Changing this to INCLUDE_DESCRIPTIONS_WITH_WHITESPACE, which feels more natural to the goals
