Ok. Thanks. I see that it is possible, though the syntax is not what I would
call pretty...
...which made me thinking, would it be possible to write something that use
the iterator interface for reading lines from a file? I.e. something like:
File f = File.open("path");
foreach (string s in f.readlines()) {
print s;
}
What exactly is an iterator? An interface? Where is it defined?
