method versus method!

Hi

Why isn't the name of the Array-method delete_at delete_at! ?

The method changes the object, doesn't it?

There are others like this, too.

The naming-convention seems to be that a (! "bang") method exists
only if there is a corresponding (non-bang) method which doesn't
modify the receiver.
