Ugly Show output appearing in error messages #97

Closed jml closed 7 years ago

jml commented 7 years ago

We should have a type class for formatting values for clients, implement that for things that we're validating etc., and then use it when generating error messages.

Show should just be for us debugging Haskell library / REPL use.
