Ranges: How to take N last of elements of range

[via Digitalmars-d-learn]

How to take N last of elements of range?

I have tried the following example in my code, but it says that 
it deprecated. What is the other possible way?

static struct LogerInfo
	{
		string func;
		int line;
		
		void write(T...)(T data)
		{
			import std.stdio;
			import std.algorithm: splitter;
			import std.range: retro;
			import std.range: take;
			import std.array: array;

			string shortFuncName = 
func.splitter(".").retro.take(2).retro.array;
			writeln( shortFuncName, "[", line, "]:  ", data );
		}
	}


It says the following:

/usr/include/dmd/phobos/std/range/package.d(224): Deprecation: 
function std.algorithm.iteration.splitter!("a == b", string, 
string).splitter.Result.popBack is deprecated - splitter!(Range, 
Range) cannot be iterated backwards (due to separator overlap).
