File.byChunk[1] should do the trick.

Not sure, if this is, what I'm looking for. I'd like to do 
something like

 buffered_file.map!(a=>2*a).writeln();

When I understand it right, with byChunk I'll have to take care 
about the end of the buffer, myself...

You could use `joiner` from std.algorithm, e.g.
     buffered_file.byChunk(4096).joiner.map!(a => 2 * a).writeln;
