Looks like Enum with reserved keyword causes problems

[elnygren]

I have a GraphQL enum with values "public" and "other".

enum Visibility {
  public
  other
}

and query similar to:

module MyThingFragment = [%graphql {|

  fragment MyThingFragment on ListedShift {
    visibility
  }

|}];

Apparently "public" becomes `public_ (note underscore) but something else is wrong in the generated code and it's still looking for `public (without underscore) as I get an error that says:

Error: This pattern matches values of type [? `public ]
       but a pattern was expected which matches values of type
         t_visibility
       The second variant type does not allow tag(s) `public

We have to add an _ to poly variants that are keywords. It looks like it is somehow not escaped everywhere in the generated code, thanks for the bug report!
