Sorry.
A solution is to introduce a "byLineFast" that is similar to
the current "byLine", and make "byLine" copy.
Another solution is to keep only "byLine" and give it a
compile-time boolean argument to disable the copy, that is
active on default.
Bye,

Given that "byLine" already exists, I'm not sure we can change it
now. But I wouldn't be against adding a "byLineSlow" or something.
However, if we could start again, I'd *definitely* favor a deep
copying "byLine" by default, and have a faster, but harder to use
"byLineFast".
