Dear fellow Haskellers who care about the usability of our language, imtringued has raised an important point here. His/her comment is quite long but the summary is: Postable is exported here https://hackage.haskell.org/package/wreq-0.5.1.0/docs/Network-Wreq.html#v:post https://hackage.haskell.org/package/wreq-0.5.1.0/docs/Networ... but defined in some internal module. Its instances are technically orphans because they are defined directly in the module that Postable is reexported from. That means that the documentation for them is detached from the documentation for the class. https://hackage.haskell.org/package/wreq-0.5.1.0/docs/Network-Wreq-Types.html#v:-36-fFormValueDouble https://hackage.haskell.org/package/wreq-0.5.1.0/docs/Networ... This is confusing and Haddock should be improved to address this.
