Main foreach loop fails when another foreach is added

[ikelaiah]

Hi,

I'm writing a program that reads a text file and launch my work 
URLs in it.
It worked fine, and very happy.

Then I added another `foreach` loop to count total number of 
lines.
After this, the main `foreach` won't work.

Does anyone know as to why this happens?
I might have missed something very obvious.

Thank you.

Regards,

     if (user_args.helpWanted)

     auto file_range = input_file.byLine(KeepTerminator.no, 
std.ascii.newline);

     // if this foreach not commented out
     // the last foreach won't run.
     foreach (char[] line; file_range)
     {
         line_count += 1;
     }

     // the MAIN foreach loop
     // -- won't run if above foreach is enabled
     foreach (char[] line; file_range)
     {
         if (!line.empty)
         {
             writeln("Open URL: " ~ line);
             Thread.sleep(dur!("seconds")(2));
             browse(line);
         }
     }

     writeln("Open URL: completed");

     writeln("Closing " ~ input_filename);
     input_file.close();
}
