This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

instance-map provides Template Haskell functions that help go from serialized values with value-level type witnesses (i.e. TypeRep values) to existential types containing type-level evidence of membership in a type class. It is useful for dealing with serialized values when only membership in a certain class (and not the monomorphic type) is known at the site of deserialization.
