// With the API support for Polyglot, we lost the ability to expose
// map operations (underlying Java Map API) as well as proxy methods
// on ECMA objects. What works now is object semantics + non-map methods.
// More testing and refinement may be needed to clarify the rules here.

// previously:
// print('params.get("one")=\'' + params.get("one") + "'"); // worked with nashorn
// print('params.get("three")=\'' + params.get("three") + "'");
// print('params.size()=' + params.size());

// Called with one=two three=four
