Question about error/completion contract with streams

[3n-mb]

Observables are commonly done to fulfill this contract
Do Stream's adhere to it? And if not, it which point is it different?

1. Error or completion may happen only once. No more events expected, after one of these happens. Do Stream's act this way?
2. If we have a chain stream.op1(...).op2(...).op3(...), and let's assume there is a parallel execution at points 1 and 3, when error happens at 3. Execution in 1 may not be stopped, its fine. But, when execution at 1 is done, will result go into point 2, to start execution there, or, will the stream flow be stopped?

[3n-mb]

It seems, from #206 that errors don't close stream.
The question is then, when v0.2 with proper behaviour is expected?

Thanks for the report! I believe this does indeed fall under #206 which is planned for the 0.2 release, so I'm going to close this.
