std.stream replacement

[BLM768]

While working on a project, I've started to realize that I miss 
streams. If someone's not already working on bringing std.stream 
up to snuff, I think that we should start thinking about to do 
that.
Of course, with ranges being so popular (with very good reason), 
the new stream interface would probably just be a range wrapper 
around a file; in fact, a decent amount of functionality could be 
implemented by just adding a byChars range to the standard File 
struct and leaving the parsing functionality to std.conv.parse. 
Of course, there's no reason to stop there; we could also add 
socket streams, compressed streams, and just about any other type 
of stream, all without an especially large amount of effort.
Unless someone already wants to tackle the project (or has 
already started), I'd be willing to work out at least a basic 
design and implementation.
