Standardized Ladder of Functional Programming

The LambdaConf Ladder of Functional Programming (LOFP) is a standardized progression of different concepts and skills that developers must master on their journey to becoming expert-level functional programmers. LOFP can be used to rank workshops, talks, presentations, books, and courseware, so that aspiring functional programmers have a better understanding of what material is appropriate for them given their current experience.

Problem Description

I'm working on an JSON/HTTP backend that uses cookie/access token based authentication, modelled after https://haskell-servant.readthedocs.io/en/stable/tutorial/Authentication.html#generalized-authentication

Now I would like to add role based authorization to the mix. The User datatype that I use in my AuthHandler has a role attribute.

As far as I understand it, the user object is added to the context when the

Gödel left in his papers a fourteen-point outline of his philosophical beliefs, that are dated around 1960. They show his deep belief in the rational structure of the world. Here are his 14 points:

1. The world is rational.
2. Human reason can, in principle, be developed more highly (through certain techniques).
3. There are systematic methods for the solution of all problems (also art, etc.).
4. There are other worlds and rational beings of a different and higher kind.
5. The world in which we live is not the only one in which we shall live or have lived.
6. There is incomparably more knowable a priori than is currently known.
7. The development of human thought since the Renaissance is thoroughly intelligible (durchaus einsichtige).
8. Reason in mankind will be developed in every direction.
