Test if lists share any items in python
I want to check if any of the items in one list are present in another list. I can do it simply with the code below, but I suspect there might be a library function to do this. If not, is there a more pythonic method of achieving the same result.

m_CursorStack.erase( --(i.base()) );
EDIT
Updating for C++11.

Can you change what a symlink points to after it is created?
...

$ ls -al test
lrwxrwxrwx 1 pascal pascal 7 2009-09-23 17:12 test -> .bashrc
