Allow node_load($nid)

I am going to +1 this.

node_load(x) is much more natural to type. Having it use an array if found is useful too though.

+1
It's not only about lazy developers -which I am ;-)- it's also about shorter code => less errors, easier to catch

I like this! Is there a similar issue for user_load()?

I definitely prefer the version where we simply allow $conditions to be passed as an integer, rather than introducing additional parameters.

It matches PHP's convention of having "mixed" argument types for some functions for shorthands (e.g. str_replace allows array arguments to compact multiple replacements in one statement). And not unimportant: it does not break backwards compatibility for what it essentially syntactic sugar.

I concurr about the mixed parameter.

let me weigh in +1 on the mixed parameter side ... let's get away from blowing up backwards compatibility unless it's justified and/or unavoidable for the sake of progress. please :)

I thought this had hit the trunk some days ago.. Chx, can you or Dries confirm and mark this issue as "Fixed"?

This has been committed. Marking it 'fixed'.
