It doesn't fit the (admittedly difficult to fulfill) desideratum that 
the obvious code is safe and fast. And the obvious code uses byLine, not 
byLine.transient.

Back to a simpler solution: what's wrong with adding alternative APIs 
for certain input ranges? We have byLine, byChunk, byChunkAsync. We may 
as well add eachLine, eachChunk, eachChunkAsync and let the 
documentation explain the differences.
