Re: Schroedinger's Ranges

a) What is the rationale behind not making byLineCopy the 
default?

byLine was the original implementation. byLineCopy was added 
later after the need for it became apparent.

See:

THX. BTW byLineCopy defaults to immutable char. That's why one 
has to use

    auto tmp = File(filename).byLineCopy!(char, char);

or

    auto tmp = File(filename).byLine.map!dup;
