Why are C# 3.0 object initializer constructor parentheses optional?
It seems that the C# 3.0 object initializer syntax allows one to exclude the open/close pair of parentheses in the constructor when there is a parameterless constructor existing. Example:

Remove all classes that begin with a certain string
...jQuery, the actual DOM element is at index zero, this should work
$('#a')[0].className = $('#a')[0].className.replace(/\bbg.*?\b/g, '');
