lean4
Lean is a functional programming language that makes it easy to write correct
and maintainable code. You can also use Lean as an interactive theorem prover.
Lean programming primarily involves defining types and functions. This allows
your focus to remain on the problem domain and manipulating its data, rather
than the details of programming.
