           Summary: JSONValue.opBinaryRight!"in" is const
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: trivial
          Priority: P1

The following code fails to compile:

JSONValue j = [ "foo": "bar" ];
if (JSONValue* f = "foo" in j) // Error: cannot convert `const(JSONValue)*` to
`JSONValue*`
        *f = "baz";

making the method inout would solve the problem:
