Actually we already have the proper check implemented here: https://github.com/vuejs/vue/blob/dev/src/core/util/props.js#L166-L169
So we can just do getType(prop.type) === 'Function'

If the prototype of a function is also a function, we treat it as
Functionconstructor.This check is context independent, so server side can safely extract vue as an external library. And it is not expensive.
Of course it is not silver bullet. Users can pass a value of which the prototype is set to a function. But naughty users can also rewrite
Functionglobal, so I think this change is at most as bad as current check.Other counter examples are welcome!
