Research direction
Start by reading the existing Data.Validation.Semigroup module and how this repository organizes and tests modules. The issue proposes a Data.Validation.Semigroup.QualifiedDo module exposing bind as andThen; confirm the expected type and add coverage for using it with qualified do notation. Done when the module supports the proposed usage and the relevant tests pass.
Written by the indexing model from the issue text.
Description
The Data.Validation.Semigroup V does not have a Bind instance because it can lead to unexpected results despite it otherwise working fine. That makes sense, but when I do want that behavior, I can use andThen. Unfortunately, it means I can't use do notation anymore.
As a workaround, perhaps a module should be added to this repo which exposes the following module?
module Data.Validation.Semigroup.QualifiedDo
import Data.Validation.Semigroup (V, andThen)
bind :: -- type signature
bind = andThen
Then, when imported as import Data.Validation.Semigroup.QualifiedDo as V, we can use V.do. Since its qualified do notation, one is able to see that something 'special' is going on with the bind calls.
