digitalmars.D.learn - How to use UFCS and std.algorithm.sort?

Hi,

with the new beta I get the warning I should use 
std.algorithm.sort instead the .sort property. I thought the 
std.algorithm.sort method is used in this example?

void main()
{	
	import std.algorithm: sort, uniq, map;
	import std.array: array;
	
	string[] arr = ["A","B","B","C"];

	string[] result = arr
		.map!(n => n) // minified
		.array
		.sort
		.uniq
		.array;
}

I want to use the sort template with the default less "a < b" 
without specifying !("a < b")

Kind regards
André

buildin arrays have a .sort-property that is called.

.sort on an array is going to use the built-in sort property. You need to
use parens if you want to use the function in std.algorithm with an array
and UFCS, e.g.

arr.sort();

Didn't know that. Nice!

Another option is to use renamed imports[1] but it is hard to come up 
with an acceptable name other than sort:

     import std.algorithm: algSort = sort, uniq, map;  // <-- HERE

// ...

     string[] result = arr
         .map!(n => n) // minified
         .array
         .algSort  // <-- HERE
         .uniq
         .array;
