Sorry to be such a pain, but two more “"” sneaked (snuck?) into the second listing… 😉
And now WordPress automagically changes my post: I meant the " token
No pain at all, thanks for the copy edit.
So do any of this methods have advantages over the other? Or is it pretty much the same thing?
Exercise left to the reader… 🙂
But I think…a decorator is associated with a specific function, whereas with with you can use with with any function that you want to pair with the undo bracket.
Sorry about all the alliteration. haha
