* Since `coffeescript` transpiles variables to `var` definitions, it uses a safety mechanism to prevent variables from bleeding to outside contexts. This mechanism consists of wrapping your `coffeescript` code inside an IIFE which, unfortunately, prevents `svelte` from finding your variables. To bypass this behavior, `svelte-preprocess` sets the [`bare` coffeescript compiler option](https://coffeescript.org/#lexical-scope) to `true`.
