reader-soup: Vinyl-based reader-like monad composition

[ combinators, control, library, mit ] [ Propose Tags ]

Packs together a stack of reader-like monads as one single ReaderT of a composite state (represented as an array). This permits to represent the entire monad stack of an application as one record (in the vinyl sense) of the parameters used to run this monad stack, and to add capabilities to that stack by just adding a new field to that record. reader-soup is part of the porcupine ecosystem.
