I feel that, though in appearance the discussion is about words like "read"
or "print" or "input", which convey actions, the core of the issue is what
primitive data format is going to have ready-made composable
parsers/assemblers. To me, as you seem to suggest, "read line" is not about
the read, it is about the line, a concept incredibly simple which hides
enough complexity to turn a line parser into a trap for the unwary. For
similar reasons, I appreciate class Properties' method load, which provides
an extremely quick way to do "property maps" when needed. For these
reasons, I think that the way for beginners is not actually about reads or
writes, but about line streamers.
