Should there possibly be a clearer error text for react/function-component-definition?

For me, the current error description ("Function component is not a function declaration") is ambiguous when using arrow functions. I've read #2505 and understand the reasoning but it is almost a matter of semantics whether an arrow function assigned to a const variable is a "declaration" or not, specially nowadays with ES6 being extremely widespread and people using both forms interchangeably. So it took me a while debugging this after upgrading some packages thinking it was something else. Maybe a note (no arrow functions allowed) or something like that would do it.

sure, improving the error message here would be a fine PR. Perhaps "non-arrow function declaration"?

That said, I'm going to close this, since it belongs filed on eslint-plugin-react, not here :-)
