	English Consider this example. As was discussed in a previous section, <<ref_is_map_like>> requires that your key type satisfies <<ref_is_string_like>>. Now, let's say your keys are not string-like, but they do convert to <<ref_string>>. You can make such maps to also convert to objects using a context. But if you want to also use another context for values, you need a way to pass the full combined context to map elements. So, you want the following test to succeed. 462/10000 · 462
