Please consider adding PyPy Trove classifiers, because apparently black works fine! At least on the recent PyPy (I tested PyPy3.6 v7.0 on macOS). I used version 18.9b0 of black. See https://pypy.org/download.html

trait FooBar {
    fn foo(&self) -> i64 {
        // some comment
        #[allow(cli

When I try to beautify the i get the following problem
TypeError: Cannot read property 'on' of undefined

I really don't know if we have some rules to create Mercosul/Brazilian license plate, but I think that we should keep support for both (after 2024 we can drop Brazilian support since Brazil will only use Mercosul format).
