Yeah, I understand. The thing is that we will remove in the near
future MultiByteFileStream.
And not all streams have conceptually a position. Today there was a mail
from Sven about that.

Perhaps #keepStateWhile or something similar might be better than
#unchangedDuring ?

I use the approach you mention, restoring stream position, in my ParrotTalk
code, both in Pharo and in Java. I am not peeking more than one character but I
had to implement peek in Java and your code example is how I did this code.

Hi Andrew,
My first hunch is that you don't want to change PositionableStream. Because
it works on collections and files (because of inheritance). But not on
other kind of streams that are not part of the hierarchy, such as sockets.
And we are cleaning that part.
Instead, some time ago Sven produ
I sometimes find, when working with a stream, that I need to "peek ahead” a few
items, without disturbing the state of the stream. The message stream peek
gives me the next item, but doesn’t generalize to multiple items, So I end up
writing code like this:
findSomething
| savedPos
