I thought of it for a bit, but couldn't come up with anything :o). I 
think you're right!

Someone proposed to add something like 
http://docs.python.org/library/fileinput.html to Phobos. I think it's a 
good idea. We have all mechanics in place (byLine/byChunk, chain). So it 
should be easy to define byLine to accept an array of filenames:

import std.stdio;
void main(string args[]) {
     getopt(args, ...);
     foreach (line; File.byLine(args[1 .. $]) {
         ...
     }
}

I hypothetically made byLine a static method inside File to avoid 
confusing beginners (one might think on first read that byLine goes line 
by line through an array of strings).
