An IO Streams Library

[Jason White via Digitalmars-d]

I see the subject of IO streams brought up here occasionally. The 
general consensus seems to be that we need something better than 
what Phobos provides.

I wrote a library "io" that can work as a replacement for 
std.stdio, std.mmfile, std.cstream, and parts of std.stream:

     Package: https://code.dlang.org/packages/io

This library provides an input and output range interface for 
streams (which is more efficient if the stream is buffered). 
Thus, many of the wonderful range operations from std.range and 
std.algorithm can be used with this.

I'm interested in feedback on this library. What is it missing? 
How can be better?

I'm also interested in a discussion of what IO-related 
functionality people are missing in Phobos.
