- A generic arrow instance binds its trailing capture locals before it lowers the declared parameters, so a parameter default that reads an immutable enclosing binding resolves it instead of failing with SC1090. The captures stay trailing parameters. - A binding is written when one of its own declarations writes it: a `var` in a for-in or for-of head (every iteration), or a redeclaration that initializes (`var x = 1; ... var x = 2;`, a parameter or function declaration that a `var` redeclares). Such a binding is now shared with generic instances through the environment form, so a closure an instance returns reads the current value instead of a copy.
