Better autocomplete support for object methods

This may be a little more towards full IDE, but it would be nice to have better autocomplete support for objects and their methods. For instance (in Java), if you have a String object named test, it would be nice to give the methods available for the object when you type the period after the object name. For example typing "test." would give autocomplete suggestions such as isEmpty() and length() and would reduce autocomplete suggestions which are not part of the object's class.
