Can you read the next line while iterating over byLine?

[John Doe via Digitalmars-d-learn]

Let's say you're trying to parse a file format like:

Name
http://example.com
123234

Foo Bar
http://dlang.org
888888

with blocks separated by varying amount of blank lines.

import std.stdio;

void main(string[] args){
     auto range = File("text.txt").byLine();

     foreach( line; range ){
         if (line != ""){
             writeln(line);
             // char[] url = range.???
             // char[] num = range.???
         }
     }
}

How can you read the next line while iterating over a file line 
by line, so that the next iteration uses the line after next? If 
this isn't possible byLine is a design flaw and D should instead 
provide a regular readLine function.

btw: What is this? A forum for a programming language that 
doesn't support code blocks?
