Q. What's the best way to insert into an STL map?

A. Assuming these declarations:

	typedef std::map<std::string, int, std::less<std::string> > StringToInt;
	StringToInt	m;

This will usually work:

	m["one"] = 1;

But this is more clear:

	m.insert(StringToInt::value_type("one", 1));

It has no chance of being confused with a fetch from the map.
