Hi Bob,

I'm afraid I don't get you. If I'm given literal string 
"{int (*)(int)} 0x12345678" by gdb, and I want to display it without "{}", 
then I surely have to remove the "{}" part, no?

Or you wanted to say I should use variable objects and traverse the tree 
structure they have? If so, can you expand on this?
