std.algorithm.splitter and std.regex.splitter can easily be 
leveraged to split lines.

However, a convenient, generic `byLine` algorithm that splits on 
any Unicode line break sequence in a carefully defined manner 
that guarantees optimal performance might be something we need to 
add to Phobos. When composing with `splitter`, the user is prone 
to introducing subtle limitations, like relying on "\r\n" vs "\n" 
or not supporting the non-ASCII line break characters, and is 
prone to introducing bugs due to subtle behaviour on empty lines.
