Best practise to handle missing interpolation values?

[Strajk]

As a developer, I would like to know when I forget to provide interpolation values. Do you have some best practice to do that?

Throwing exception is probably too much, but a warning is too little :)

polyglot.extend({
  "hello_name": "Hola, %{name}."
});

polyglot.t("hello_name", {});
=> "Hola, %{name}." // => 💣💥

Sometimes this is intentional - for example, if you're sending a partially interpolated string from the server to the browser to finish there. Do you have a suggestion?

In general tho this seems like the kind of thing that's addressed with testing.
