nr-stream

The `nr-stream` package provides utilities for writing functional-style code in Python, offering `Stream`, `Optional`, and `Refreshable` classes. The `Stream` class wraps iterables to enable chained modifiers, simplifying common operations. `Optional` represents a value that might be `None`, allowing for safe chaining, while `Refreshable` acts as a container for values that can be updated, propagating changes to listeners. The current version is 1.1.5, released on February 14, 2023, with an active but irregular release cadence.
