The big downside is the verbosity of the approach: A lot of parameters need to be passed, and if one such value is suddenly required in a function where it was not before, this function’s signature and all functions using it have to be modified. Also, I expect that the explicit passing causes a small performance penalty.
Can't this be mostly solved by putting all these configuration parameters in a struct and then using implicit parameters: http://www.haskell.org/ghc/docs/latest/html/users_guide/other-type-extension... The nice thig about this approach is that is not a single unsafe operation needed.
