[phobos] Improvement of stream

[SHOO]

Hmm... Does it mean to have to relay three classes to do I/O processing?

auto handle = FileHandle("file");
scope (exit) handle.close();
auto buf = MemoryBuffer();
auto range = byLine(range);

I think it is slightly complicatedly. What is the reason why it must 
come to look like it?

BTW, I don't know well what buffers must do. What is the requirement of 
buffers?
