Should prohibited keywords includes `this`?

What problem does this feature solve?

From vuejs/eslint-plugin-vue#148.

Vue.js has prohibited keywords, but it does not include this (though it includes super).
My feeling is that the use of this causes confusing.

Are there reasons that the prohibited keywords don't include this?

What does the proposed API look like?

The prohibited keywords include this keyword.

Sounds reasonable. Especially when vue automatically prefix template identifiers with this.

I actually sometimes use this for demonstration purposes for people coming from react background. I don't think it should be prohibited since it works perfectly fine. Rather it should be a part of eslint-plugin-vue and be "recommended" instead of "forbidden".

P.S. just though about this now, @HerringtonDarkholme do you think it's reasonable to remove do (and let) from prohibited keywords? Does it make sense to support do expression? (ex: @click="myMethod(do { let tmp = f(); tmp * tmp + 1 })")

@nickmessing For let and do, I don't think we should allow them since it can promote more inappropriate logic in template. Like the example you give, I would think it probably belong to a method on vm.

Ah, I see. I didn't realize this. prefix works fine.

Since some users actually use this inside templates, prohibiting it will be a breaking change. As @nickmessing suggested, I think it would be better to make this a rule in the eslint plugin instead.
