Description GSkachkov 2015-10-08 14:31:55 PDT

It would be nice to implement syntactic analysis for arrow function that 'tells' if arrow function use 'this'.Something similar to usesThis(). It should check if 'this' or eval is used inside of body arrow function. This property will allow to avoid unnecessary allocations, checks and emits.

Is there still something that needs to be done here?
