What is the problem?

export interface IFoo {
  bar(): string;
  readonly baz: number;
}

export class Base implements IFoo {
  public readonly baz = 120;
  public bar() {
    return 'bar';
  }
}

export class Derived extends Base implements IFoo {
  public zoo() {
    return 'zoo';
  }
}

This results in the following error:

#STDERR> # github.com/aws/jsii/jsii-calc/go/jsiicalc/v3/module2700
#STDERR> module2700/module2700.go:72:9: jsiiProxy_Derived.Bar is ambiguous
#STDERR> module2700/module2700.go:72:9: cannot use &j (type *jsiiProxy_Derived) as type Derived in return argument:
