  • Monad Transformers and Effects with Backpack
    3 projects | | 24 Dec 2020
    What would be the advantage of having signatures of such fine granularity vs. having a big signature for your program logic which describes a monad with all the required MonadState, MonadReader... interfaces, and then an implementation module which assembles the whole monad transformer stack in the usual way? Something a bit like this?
