I noticed the following two comments inrule.spec.ts:

1. eslint-plugin-prefer-arrow-functions/test/rule.spec.ts

   Line 152 in08712f5

   // assertion functions are unavailable in arrow functions

2. eslint-plugin-prefer-arrow-functions/test/rule.spec.ts

   Line 156 in08712f5

   // function overloading is unavailable in arrow functions

I don't know the exact context for these, so this might be a frivolous issue, but AFAIK it's certainly the case that both of the aforementioined TypeScript features (assertion functions andfunction overloading) work perfectly fine as arrow functions.

There might be edge cases or complications to applying it as an eslint rule that I haven't thought of here, but on the face of it: the statements made in those two comments don't strike me as correct.

As for a fix: I'm not sure if the problem here is really just the phrasing of the comments themselves, or if this is a more worthwhile issue (meaning: perhaps it turns out that wecan do some automatic conversion for either/both of these types of functions as well, which would be great news).
