arrows and a proposed softCall

[Irakli Gozalishvili]

I would also like to express that I think => with proposed (bound this) semantics, are great. And I don't think it introduces any new issues it's just a sugar for:

function() {  /* … */  }.bind(this)

Dynamic |this| allows for functions to work like methods - it enables mixins and all kinds of meta-programming goodness. However, it can also be abused, and create really funky code that can lead to weird surprises.

I suppose I can see the appeal of not having to add that pesky extra parameter and instead use |this| for whatever arbitrary thing you might want to put there, but it sure seems less readable to me. You might as well just use the arguments object for everything instead having parameter names!

That is one use of call/apply, and one that will hopefully need less use. Another nice use of it was to easily delegate by using apply and passing through the arguments object. That will go away with rest parameters. So yeah, we might be seeing less of call/apply with ES6, but I think we're replacing them with better patterns instead of just saying they aren't useful anymore.
