Good point. I'm removing this entirely. I'll just use casting in place, e.g.
**Example 1**
`String val = (String) map.get("foo"); // throws class cast exception on
failure, which is what we want`
**Example 2**
```
Map<Object, Object> a = new HashMap() {{
put("hello", "world");
put(1, 2);
}};
Map<String, Object> b = new HashMap() {{
put("a", a);
}};
Map<Object, Object> c = (Map) b.get("a"); // throws class cast exception if
not a Map
Map<String, String> d = new HashMap<>();
for (Map.Entry<Object, Object> entry : c.entrySet()) {
d.put((String) entry.getKey(), (String) entry.getValue()); // throws
class cast exception. also what we want
}
```
