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;


That's it. Thanks!

Files as buffered InputRange

I'd like to process a (binary) file as a buffered InputRange but 
I havn't found anything yet.  Is there anything or do I have to 
write it on my own?
