BREAKING CHANGE
Before:
@Directive({selector: '[credit-card]', bindings: [new Binding(NgValidator, {toAlias: forwardRef(() => CreditCardValidator)})]})
class CreditCardValidator {
get validator() { return CreditCardValidator.validate; }
static validate(c): StringMap<string, boolean> {...}
}
After:
function creditCardValidator(c): StringMap<string, boolean> {...}
@Directive({selector: '[credit-card]', bindings: [new Binding(NG_VALIDATORS, {toValue: creditCardValidator, multi: true})]})
class CreditCardValidator {}
