package rocq-stdpp

The key features of this library are as follows:

• It provides a great number of definitions and lemmas for common data structures such as lists, finite maps, finite sets, and finite multisets.
• It uses type classes for common notations (like ∅, ∪, and Haskell-style monad notations) so that these can be overloaded for different data structures.
• It uses type classes to keep track of common properties of types, like it having decidable equality or being countable or finite.
• Most data structures are represented in canonical ways so that Leibniz equality can be used as much as possible (for example, for maps we have m1 = m2 iff ∀ i, m1 !! i = m2 !! i). On top of that, the library provides setoid instances for most types and operations.
• It provides various tactics for common tasks, like an ssreflect inspired done tactic for finishing trivial goals, a simple breadth-first solver naive_solver, an equality simplifier simplify_eq, a solver solve_proper for proving compatibility of functions with respect to relations, and a solver set_solver for goals involving set operations.
• It is entirely dependency- and axiom-free.
