Title: chore: Make field declarations explicit

This used to be valid code:

class Foo {
constructor() {
this.bar = ‘string’;
}
}

This will now fail since ‘bar’ is not explicitly
defined as a field. We now have to write:

class Foo {
bar:string; // << REQUIRED
constructor() {
this.bar = ‘string’;
}
}
