One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

#include <sys/time.h> // for gettimeofday()
class StopWatch {
timeval started;
std::string msg;
public:
StopWatch(const std::string& m): msg(m)
{ gettimeofday(&started, NULL); }
