[flippidippi]

Will the unsafe TS checks ever be added? They are recommended by typescript-eslint via plugin:@typescript-eslint/recommended-requiring-type-checking

  '@typescript-eslint/no-unsafe-argument': 'error',
  '@typescript-eslint/no-unsafe-assignment': 'error',
  '@typescript-eslint/no-unsafe-call': 'error',
  '@typescript-eslint/no-unsafe-member-access': 'error',
  '@typescript-eslint/no-unsafe-return': 'error',

[mightyiam]

Thank you, @flippidippi.

@rostislav-simonik and I reviewed the rules you asked about and we are in favor of them being added.

Would you like to submit a pull request adding them?

While we are at it, may as well add no-unsafe-declaration-merging because we reviewed that, as well.

[flippidippi]

It looks like no-unsafe-declaration-merging would require an upgrade. Should that be done in a different PR?

[mightyiam]

@flippidippi an upgrade of what, please? This project has automatic dependency upgrade PRs by renovate. So I don't expect our dependencies to be out of date.

[flippidippi]

@typescript-eslint/parser would need to be upgraded to include the newer no-unsafe-declaration-merging rule.

[mightyiam]

Oh... you're right. There seems to be a discrepancy. I expect to receive a PR for updating the parser automatically. I don't see one, though.

So, feel free to proceed without that rule, then.
