Name "__debug" must not begin with "__", In a future release of graphql this will become a hard error.

it's popped from graphiql graphiql.min.js:1 Name "__debug" must not begin with "__", which is reserved by GraphQL introspection. In a future release of graphql this will become a hard error.

Adding to the current project so we can resolve this.

@phalt what is your proposition about solution? _debug or anything else?

[phalt]

@dulmandakh I don't have a solution yet myself, I'm moving it to the improvements project so we can focus on it. Do you have a suggestion?

[dulmandakh]

@phalt create a PR, please see #646
