Search for class instances #349

Open yaitskov opened 4 years ago

yaitskov commented 4 years ago

Hi,

I guess it would be cool to have an ability to search for orphan class instances. For example I looking for a library which could convert AST to String or Json.

"instance ToJson (HsExpr )" "instance Show HsDecl "

Orphan instances in Haskell are super discouraged. Having them in libraries often causes people to be bitten later - both with conflicts and because they are hard to find. I'm not sure they are popular enough to support specially.
