scope file.open

[nobody]

Hallo,

how can i saftly open a file with scope.
My  idea is:
import std.stream;
import std.stdio;

void main() {
        File file = new File;

        scope(failure) {
                writefln("Datei kann nicht geoeffnet werden ");
        }
        file.open("testdatei.txt",FileMode.In);

        while(!file.eof()) {
                printf("%.*s\n",file.readLine());

        }
        file.close();
}


But why must scope(failure) before the file.open statement.
I think it's look strange.
Mybe some on have a better idea to open a file with scope.

Sincerily
