This would essentially mirror the approach of https://github.com/JuliaOpt/MathProgBase.jl .  Would it be worth trying to hammer out this interface in this road-map issue?\r\n\r\nEdit: By \"same interface\" I don't mean that ODE and DAE solvers have the same interface.  But that all ODE solvers are wrapped to conform to the same interface (similarly all DAE, and maybe all IMEX, etc).  So, Sundials.jl, ODE.jl, etc. would then depend on `ODEProgBase` (or probably `DiffEqBase`) and extend some `solve` function there, taking as input some problem specification type.  Likewise all higher level Diff-Eq stuff (currently DifferentialEquations.jl and IVPTestSuite.jl) would program against this interface.\r\n\r\n### TODO\r\nSpecify:\r\n- [x] `solve` signature: `solve(p::Problem, ::Type{Alg}; kwargs...)`\r\n- [ ] `Problem` types\r\n- [ ] `Solution` types\r\n- [ ] default options\r\n- [ ] callback options"},"comment":{"url":"https://api.github.com/repos/JuliaDiffEq/Roadmap/issues/comments/259668926","html_url":"https://github.com/JuliaDiffEq/Roadmap/issues/5#issuecomment-259668926","issue_url":"https://api.github.com/repos/JuliaDiffEq/Roadmap/issues/5","id":259668926,"user":{"login":"ChrisRackauckas","id":1814174,"avatar_url":"https://avatars.githubusercontent.com/u/1814174?v=3","gravatar_id":"","url":"https://api.github.com/users/ChrisRackauckas","html_url":"https://github.com/ChrisRackauckas","followers_url":"https://api.github.com/users/ChrisRackauckas/followers","following_url":"https://api.github.com/users/ChrisRackauckas/following{/other_user}","gists_url":"https://api.github.com/users/ChrisRackauckas/gists{/gist_id}","starred_url":"https://api.github.com/users/ChrisRackauckas/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ChrisRackauckas/subscriptions","organizations_url":"https://api.github.com/users/ChrisRackauckas/orgs","repos_url":"https://api.github.com/users/ChrisRackauckas/repos","events_url":"https://api.github.com/users/ChrisRackauckas/events{/privacy}","received_events_url":"https://api.github.com/users/ChrisRackauckas/received_events","type":"User","site_admin":false},"created_at":"2016-11-10T11:38:23Z","updated_at":"2016-11-10T11:38:23Z","body":">My experience is that type annotations generally help a bit but not 100%.\r\n\r\nAnnotations are very different from declarations.
