Yeah, for sure. That's certainly possible, but I rarely see people build for it, at least when it comes to value types like strings, ints, etc.

One other thing that I DO like about type-less, is the ability to introspect, for example, in PHP:

``` foreach ((array) $my_class as $property => $value): ```

vs. a bunch of boilerplate and making sure types match up in most strongly-typed languages.
