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

[Adam D. Ruppe]

If byLine returned a scope item, then it wouldn't be allowed to 
escape and throw a nice compile error pointing people in the 
right direction.... scope rox so much i want it so badly. (i 
guess here the mutability pretty much tells the story too tho)


But going with the idea that the duplicated one can be 
escaped/stored:

f.byLineStorable

or something like that. The name tells you that it is cool to 
store each line.
