Drupal: EntityMetadataWrapper auto-completing code

Using entity_metadata_wrapper() from the Entity API module has a lot of advantages discussed all over the internet, but it has been bugging me for quite some time that the wonderful switch from array structures to OOP has not solved one of the obvious problems - no auto-completing code in the editor.

A very quick glance into the entity_metadata_wrapper() function showed me that this can be easily solved (at least partially) - with EntityDrupalWrapper.
The thing is, that entity_metadata_wrapper() returns an object based on provided arguments.
The “old” way:

1
2
3

<?php
$node_wrapper = entity_metadata_wrapper('node', $node);
?>

Since entity_metadata_wrapper() can return different object types, your IDE cannot determine which one actually gets returned and therefore does not provide proper auto-completing. If EntityDrupalWrapper is used directly, this problem goes away and you can enjoy at least some basic auto-completing of methods.
The EntityDrupalWrapper way:

1
2
3

<?php
$node_wrapper = new EntityDrupalWrapper('node', $node);
?>

Result:

This unfortunately adds auto-complete for the basic methods only, you still need to type your field names manually.

Important:
Use this only when you know what you are doing and when you are sure that entity_metadata_wrapper() would return EntityDrupalWrapper anyway - this only happens when you pass a valid entity type like node or user as the first parameter.
