I had this issue recently when reading from a command-line-style
TCP connection; I needed to read the line up to the \n separator,
but consuming the separator meant waiting for the next byte that
would never arrive unless a new command was sent.
So I made a wrapper range that evaluates the wrapped range's
popFront only when front/empty is first called ("just in time").

You can throw it in a UFCS chain anywhere except (for some
reason) after something that takes a delegate template parameter
like map. For example:
auto reader = SocketReader(socket).joiner.jitRange.map!(byt
=> cast(char) byt);
