Is it just me who finds this poor style and potentially confusing:
<?phpfunction my_function($nodes) { foreach ($nodes as $nid) { // do stuff }}?>
To me, a variable names $nodes will be an array of nodes -- that is, node objects. If it's an array of nids, I would call it $nids to avoid confusion about what we have there.
I'm curious if other people agree (in other words, is it worth my time writing a patch for core or will it just lead to bikeshedding?)
