[pypy-dev] cannot use "id" in Rpython

[Shubha Ramani]

It's not a bad idea for me. I'm hooking up to a tool made by intel called "vtune" which requires the function name, function size and function address from the original python script code. I got the first two from Python reflection (the way VmProf does it) but I need the third (original script function  address). Is __repr__ supported in Rpython ? The string returned by __repr__ contains the Python address at least in Python. If id() doesn't work but __repr__ does then I can use it in the overloaded execute_frame and that should be fine.
