Alternatively you can use std.stdio.byLineCopy and don't need to 
add the `to!string`. If you are calling to!string on ever line 
there will probably be no performance difference, but if you are 
not, such as only calling to!string on every *second* line or 
something like that, you should stick with byLine and calling 
to!string when needed.
