/**
* I've hit a bug with the caching in flow_js.ml. Avik is removing that caching
* so it should be fixed soon. The basic idea is I flow something like
*
* Array<any | any> ~> Iterable<string>
*
* then Flow won't notice when I try to flow
*
* Array<string | number> ~> Iterable<string>
*
* We shouldn't hit the cache because the union types are different, but we do
* anyway. I've fixed this temporarily by bumping the "meaningful" param to
* Hashtbl.hash_param
