I'm increasingly convinced that input ranges which are not
forward ranges are
useless for pretty much anything other than foreach.

That's already a pretty big usage :) The thing is you just can't
"do" anything with them, but that *is* the design.
Just read them once to place them into another container. The
fact they interface with, say "array", or "appender", or copy,
makes the interface convenient.
The fact that byLine will choke on a call to "array", IMO, has
nothing to do with it being a forward range.
