But I want make like it witout use variable name.

"Hello World"[0..?.indexOf("o")]

The exact syntax you want is impossible. The closest you can get 
is to use an `enum` constant, which is essentially a named 
literal:

enum hello = "Hello World";
writeln(hello[0 .. hello.countUntil("o")]); // "Hell"
