There was a problem hiding this comment.
this seems to suggest that there will be places that props and nextProps are interchangeable - that doesn't seem right to me.

I did exactly like the prop-types rules. It means that this one is wrong too.
What do you suggest? This regex is only used one time.

I pushed a try. I split the regex into 2 variables. It leads to more conditions. Tell me if you prefer this version.

there's no need to use babel-eslint here; let's just use normal Hello.propTypes = , and use the default parser

Fixes #1079
I did the same comparisons as the
prop-typesrules (https://github.com/yannickcr/eslint-plugin-react/blob/b64648521f9a7949eef4cd1a210768e906b4f3d1/lib/rules/prop-types.js#L130) for theno-unused-prop-typesrule.This way they both handle nextProps identically.
I also borrowed the test case from #1105.
