Yes, I've missed this and if Kevin already studied real world use cases and that's the result then it's OK.
What is misleading about this topic is that it looks like a shortcut for common functions but it is absolutely not like that and this should be emphasized quite a lot, IMO We have function, function with a `this` in it, bind with `this` made immutable and arrow with `this` made immutable and not the whole closure in it ... this is a very specific and different thing I need to get familiar with. I will, eventually.
