-GDScript can bind an array of values to connections between a signal
-and a method. When the signal is emitted, the callback method receives
-the bound values. These bound arguments are unique to each connection,
-and the values will stay the same.
+You can also create copies of GDScript Callable objects which accept additional
+arguments using :ref:`Callable.bind() <class_Callable_method_bind>`. This
+allows you to add extra information to the connection if the emitted signal
+itself doesn't give you access to all the data that you need.
 
-You can use this array of values to add extra constant information to the
-connection if the emitted signal itself doesn't give you access to all the data

+When the signal is emitted, the callback method receives the bound values, in

 Building on the example above, let's say we want to display a log of the damage
 taken by each character on the screen, like ``Player1 took 22 damage.``. The
 ``health_changed`` signal doesn't give us the name of the character that took
 damage. So when we connect the signal to the in-game console, we can add the
-character's name in the binds array argument::
