You don't need to do anything special for that in D, structs are
destructed automatically. Plain
auto file = File("some_file.txt");
file.write();
will automatically close file when it goes out of scope. If you
want it to go out of scope earlier, you can:
{
auto file = File("some_file.txt");
file.write();
}
the curly braces around it will make a new scope, so the
destructor, which closes the file, will be called at the }.
