Hi, judging by my eslint failing, it seems that acorn doesn't yet support dynamic imports with assertions: ```js import('./package.json', { assert: { type: "json" } }); ``` This syntax is currently in [stage 3](https://github.com/tc39/proposal-import-assertions) so maybe it's out of scope for now – is there a policy on when things get implemented?
