dmd 2.064(.2 I think)

Docs say:
- std.stdio.byLine returns an input range
- std.array.array takes an input range

So you need to do a duplication for each element. Use this code:

-----
import std.stdio;
import std.array;
import std.algorithm;

void main()
{
     auto lines = File("test.d").byLine.map!(a => a.dup).array;
     writeln(lines);
}

so array copy the copied fronts?

Sorry, but I really don't understand this. At all.
"Returns a newly-allocated dynamic array consisting of a copy of 
the input range" to me sounds "Hey, I'm doing a copy". How is one 
supposed to understand that you need to go through hops for 
getting a good result?

Beside the answers that others have already given you, another 
way to do that is to read the whole file (with read or readText) 
and then use splitlines on the string.
