When true, the class being wrapped is class style. Our es5 wrapper depends on calling the constructor without new, so we have to differentiate.

post :ConstructorHookFunction|null
As with ClassWrapSpec.pre, this function will be applied subsequent to invoking the wrapped class's constructor.

pre :ConstructorHookFunction|null
When wrapping a class based object, the pre function will be invoked with the class's constructor arguments before the class constructor is invoked. The this reference will be bound to null.

class Foo {
constructor(a, b, c) {
// do stuff
}
}
const spec = new ClassWrapSpec({
pre: function (...args) {
// args = [a, b, c]
}
})
const wrappedClass = class Wrapper extends Foo {
constructor() {
spec.pre.apply(null, [...arguments])
}
}
