Thanks Stef,

I imagine that sven did not add it because on infinite stream it does not make sense.

Just to clarify my earlier email, I got here was by calling `'/path/to/some/file' asFileReference binaryReadStream` which responds with the ZnBufferedReadStream. I expected to be able to use something like #upToAll: to find binary-formatted headers etc within some encoding structure. It's entirely possible that this was the wrong expectation!

This method is really useful for parsing files -- finding sub-patterns of bytes, etc. Perhaps #upToAll: is not the idiomatic way to do this, but I found it very useful to use in the plain old ReadStream classes.

Now it would be good to see how we can have useful extensions. But I let this to sven.

Right now to sven repo. In the future we want to have better tools to sync back from a project to its components.
