One thing I'd like in a buffered input API is a way to perform

check for a desired length, but what I'd I don't want to read until a
full line is available, and I don't know the exact length? Typically,
you end up having to double buffer, which stinks.
std.stdio.byLine()
That was just an example. What if I want to do a formatted read and I'm
reading from a file that someone else is writing to? I don't want to block
or get a partial result and an EOF that needs to be reset.
Then you'll need an input range that can be reset - a ForwardRange.
