fructose's Issues

Functional lenses

Lenses provide a convenient and composable way to access values in deep, immutable structures.

Move quantum simulator to separate repo

The quantum computing API does not fit very well into this project as it is too specialized to be considered part of a general-purpose utility collection.

Implement Observable collections

Although Observable<T> provides a basic implementation of the Observer pattern, it would be useful to have more fine-grained observer classes, especially collections.

• ReadOnlyObservableList
• ReadOnlyObservableSet
• ReadOnlyObservableMap
• ObservableList
• ObservableSet
• ObservableMap

CI and deployment

Connect a continuous integration server to this project and (preferably automatically) deploy to an external repository.

Functional Monads

Java 8 provides the built-in Optional type, but it would be nice have further Monads like:

• NonNull<T>
• Either<A, B>
• Improved Lazy<T> (implement map and factory methods)
• Result<T, E> (storing a value or an exception - similar to Either)
