std.array.array will never work with ranges with a transient front unless it
somehow knew when it was and wasn't appropriate to dup, which it's not going
to know purely by looking at the type of front. The creator of the range would
have to tell them somehow. And even then, it wouldn't work beyond the built-in
types, because there's no generic way to dup stuff.
So, either std.array.array will not work directly with byLine or byChunk, or
byLine and byChunk need to not have transient fronts. If them not working with
std.array.array is too un-user-friendly, then they need to be changed so that
they don't have transient fronts, and transient fronts should just be
considered invalid ranges (though there's no way to actually test for them, so
anyone who wrote them would still be able to try and use them - they just
wouldn't work).
