//So the compiler was seeing $cuser->id as an index into the array $course->users
//$cuser->id is normally too large to be used to index into $course->users
//unset was not working because the index $cuser->id was out of range (larger than the size of $course->users)
//
///*unset($course->users[$cuser->id]);*/
//solution has been reimplemented below, and it should now work (hopefully)
