Re: [Pharo-users] Peeking at a stream

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. On Mon, Nov 13, 2017 at 2:48 PM, Prof. Andrew P. Black wrote: > > > On 2 Nov 2017, at
