 623
 624 @item Type classes for common notations (like ∅, ∪, and Haskell-style monad
 625 notations) so that these can be overloaded for different data structures.
 626
 627 @item It uses type classes to keep track of common properties of types, like
 628 it having decidable equality or being countable or finite.
 629
 630 @item Most data structures are represented in canonical ways so that Leibniz
 631 equality can be used as much as possible (for example, for maps we have m1 =
 632 m2 iff ∀ i, m1 !! i = m2 !! i).  On top of that, the library provides setoid
 633 instances for most types and operations.
 634
 635 @item Various tactics for common tasks, like an ssreflect inspired done tactic
 636 for finishing trivial goals, a simple breadth-first solver naive_solver, an
 637 equality simplifier simplify_eq, a solver solve_proper for proving
 638 compatibility of functions with respect to relations, and a solver set_solver
 639 for goals involving set operations.
