[polari] cleanup: Disambiguate assignments in arrow functions

[Florian Müllner <fmuellner src gnome org>]

commit 74f2a7fa30e66a8d8fecbea5520ed7c4da0e276f
Author: Florian Müllner <fmuellner gnome org>

    cleanup: Disambiguate assignments in arrow functions
    
    As arrow functions have an implicit return value, an assignment of
    this.foo = bar could have been intended as a this.foo == bar
    comparison. To catch those errors, we will disallow these kinds
    of assignments unless they are marked explicitly by an extra pair
    of parentheses.
