Good name for f.byLine.map!(x => x.idup)?

[Andrei Alexandrescu]

A classic idiom for reading lines and keeping them is f.byLine.map!(x => 
x.idup) to get strings instead of the buffer etc.

The current behavior trips new users on occasion, and the idiom solving 
it is very frequent. So what the heck - let's put that in a function, 
expose and document it nicely, and call it a day.

A good name would help a lot. Let's paint that bikeshed!
