[beginner] Why nothing is printed to stdout ?

[Frédéric Galusik]

Hi,

Can someone give me a clue on why nothing is printed to stdout ?

I wish a list of files with their size.
 
code:
//
import std.stdio;
import std.file;

void main(string[] args)
{
    foreach (DirEntry e; dirEntries(".", SpanMode.shallow))
    {
        writeln(e.name, "\t", e.size);
    }
}
//
Build with (dmd2):
dmd -w test.d
