Witold, this it not the advice that we give to people exploring such problems in Elm. There are many reasons why Native bindings are bad. A single error in your JS will cause the _entire_ application to crash unrecoverably. Wrapping things as a result will not help you catch those errors. Writing carefully thought out and tested code will. While there are cases where a Native function helps out a lot, it should _never_ be the first thing to reach for.
Dwayne, I suggest discussing things on the Elm Slack. It will be easier to get to the exact use case you have for your formatting issue.
