Functional programming constructions for Java.

Provides the core monadic types:

• Option — represents an optional value
• Result — represents a value or an error
• Either — neutral disjoint union of two value types
• Try — represents a computation that may throw
• Validated — error-accumulating validation type
• CheckedSupplier — supplier that may throw checked exceptions
• CheckedRunnable — runnable that may throw checked exceptions
• CheckedFunction — function that may throw checked exceptions
• CheckedConsumer — consumer that may throw checked exceptions
• Tuple2 — an immutable pair of two values
• Tuple3 — immutable triple of three values
• Tuple4 — immutable quadruple of four values
• TriFunction — function accepting three arguments
• QuadFunction — function accepting four arguments
• Lazy — lazily evaluated, memoized value
• NonEmptyList — list guaranteed to contain at least one element
• NonEmptyMap — map guaranteed to contain at least one entry
• NonEmptySet — set guaranteed to contain at least one element
• Guard — composable predicate blocks for Validated pipelines
• Resource — composable managed resource with guaranteed release
• Accumulator — value paired with a side-channel accumulation (Writer monad)

The entire module is @NullMarked: all API types are non-null by default.
