What is a fully type-inferred language? and limitations of such language?

The limitation of full type inference is that it doesn't work with many advanced type system features. As an example consider Haskell and OCaml. Both of these languages are almost fully type inferred, but have some features that can interfere with type inference.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
