code: public static <T, U, R> BiFunction<T, U, R> biFunction(CheckedBiFunction<T, U, R> function) {
          return biFunction(function, THROWABLE_TO_RUNTIME_EXCEPTION);
      }
docs: Wrap a {@link org.jooq.lambda.fi.util.function.CheckedBiFunction} in a {@link BiFunction}.
  <p>
  Example:
  <code><pre>
  map.computeIfPresent("key", Unchecked.biFunction((k, v) -> {
  if (k == null || v == null)
  throw new Exception("No nulls allowed in map");
  
  return 42;
  }));
  </pre></code>
