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).

You can do following http://dpaste.dzfl.pl/41c57f89a5a0
The reason of compile error is your using a range as a separator, change it to single symbol and it works. Also I used 'array' after 'take' to make range bidirectional to let next 'retro' works. And 'join' joins result to string with '.' as a separator.

Thanks for reply. This is useful
