Well, it does complicate the return value a lot though; if you
have to return an array of objects instead of a single one,
the code would not look as nice.

e.g. to use it if it only accepted one object:

foreach ($folder_list as $folder) {
   $ret = IMP_folder::delete($folder, ...);
   <process ret object>
}

or if it accepts an array and returns an array of
PEAR::Error objects (or whatever):

$ret_list = IMP_folder::delete($folder_list, ...);
foreach ($ret_list as $ret) {
   <process ret object>
}

I prefer the former; you are processing the return immediately
after the call, and not getting a bunch of them back (suppose
one folder deletion fails; you might want to halt immediately
instead of trying the other ones)
