This extra proof is necessary because it is impossible in general to automatically
prove that a given executable code satisfies an arbitrary specification. It can be
said that dependent type systems turn, at least in principle, programming into fully
formalized mathematics. Actu- ally, the languages arisen from this trend are
functional programming languages, for example Agda [Nor07], Coq [Coq09] or
Idris [Bra13], derived in general from (constructive) type theory, a system of logic
intended ...

Verification and propagation of these constraints is handled by type inference,
which can be enhanced by customised decision procedures or external solvers if
needed. The approach thus supports the development of software models that ...
Agda is a functional programming language similar to Haskell but with a much
more powerful type system in which intuitionistic higher-order logic can be used
for expressing type constraints. Since, in this context, type inference is

Haskell programs are translated into an Agda model of their semantics, by
translating via GHC's Core language into a monadic form specially adapted to
represent Haskell's polymorphism in Agda's predicative type system. ...

This paper shows that an SMT-based program verifier can support reasoning
about co-induction—handling infinite data structures, lazy function calls, and user
-defined properties defined as greatest fix-points, as well as letting users write co-
inductive ... Coinduction, too, is important in programming and program
verification, where it arises in data definitions (e.g., lazy data structures [34]),
semantics (e.g., concurrency [32]), and proofs (e.g., showing refinement in a co-
inductive big-step ...

The main motivation for all these systems, apart from the satisfaction of bringing
mathematical objects "into life", is that the non-imaginative mechanical
verification of a proof rules out the possibility of errors to a much higher degree
than the relying on ... 1.3 Conversion Rule The logical formalisms underlying
systems like NuPRL, Agda, Alf, Lego, PVS or Coq have an important feature in
common. First, the language of objects of these formalisms includes a
programming language.
