[development] programmatic creation of node

[Novák Áron]

Hi!

While the development of FeedAPI, i faced with a problem. FeedAPI has to 
create nodes programmatically, i believed that this is a really easy thing to 
do, feedapi now works like this:
$node->data1 = "foo";
$node->data2 = "bar";
node_object_prepare($node); // this is about the default values
node_save($node);

But I got a report that this is not a good way to do: 
http://drupal.org/node/196273
Summary: 
"node_object_prepare() and node_prepare() functions are meant to simulate the 
demonstration of a node"
And some users, who use FeedAPI + 3rd party modules together, really 
experience bugs around node creation / handling:
http://drupal.org/node/195105 (summary: the core forum module uses form_alter 
to pass taxonomy-like data. And this data is lost now.)

Can you suggest me a perfect way to handle this problem?
mustafau (http://drupal.org/user/207559) suggested to use 
drupal_execute($form_id, $form_values), but in this case, i had another 
problem: drupal_execute has no useful return value and $node structure 
remains unaltered, so i had to do a node_load after this, which is quite 
expensive.

Thanks,
