You can't do that, because not all streams support positioning

When loading in a stringlist you know that you must copy the whole
stream at once. With readln this is not possible: you don't know how
much you need in advance.
It's simply not possible at the TStream level.
So readln / writeln is not possible with streams. This is a problem.
I'm actually loading a file, but I wanted to use streams internally to
increase flexibility; I might exchange data with memory streams on the
long run.
