Well well well... I've long liked the look of gdb 7 and its python scripting, and now it is looking better and better! I like it when I can retire a longstanding problem. (Luckily there's never any shortage of further problems to replace it with, so I won't run out of things to talk about.)
Now seems doubly annoying that Apple make you use lldb or crappy old gdb 6 for iOS.
