Binding uses this in static method

[DubbaThony]

Trace:
PHP Fatal error: Uncaught Error: Using $this when not in object context in /home/user/gh/foo/src/Contract/Contract.php:30
Stack trace:

Issue:

There is validator generated into binding for uintN (it's sizes etc.) It's called with $this, while it can be easily static call.
