This is a minor issue. I was wondering if we can or should address warnings shiowing up in the [default examples](https://github.com/purescript/trypurescript/tree/master/client/examples). ## Warnings    ## Options * Keep the examples as they are and show the warnings * Change the code examples (e.g. add type annotation to `main`) * Change Try-PureScript to hide these specific warnings (main type signature, TryPureScript import)
