jOOL

Provides type-safe tuples from Tuple1 to Tuple16, enabling clean modeling of multi-valued returns and function arguments, a feature missing in standard Java.

Extends JDK functions with Function1 through Function16, reducing boilerplate for operations with more than two parameters, as highlighted in the README.

Seq interface adds 50+ methods like concat, cycle, and SQL-style joins, making stream manipulations more expressive while maintaining order and simplicity.

Unchecked class wraps lambdas to transparently propagate checked exceptions, eliminating verbose try-catch blocks, as demonstrated with file handling examples.
