Not from the information here:(

The expression:

   Object _objectForOop: 3526913

can be inspected and in this case will bring up an inspector on the Object

In tODE you would do the following:

  gs objectFor 3526913; edit

to get in inspector up on an object given an oop...

Good question... the `0x7f7fb6918553=@natCode+0x133` is the offset into the
native code, for the method which is not much help ... I do believe that
here in development we can interpret that information for our own methods
...
