Using variables with Kotlin closures

[GeorgEchterling]

The documentation provides an example for the usage of variables in the non-closure code.

I cannot find a way to do this when using generateKotlinClosureProjections = true, since the generated methods do not have any similar ...Reference parameters. I also cannot simply fall back to selectively using ...GraphQLQuery classes, since the generation of the Java classes seems to be mutually exclusive with Kotlin closures.

Is this feature planned and/or would you be willing to accept a PR for this feature?
