Re: MooX::HandlesVia problem

To partially answer my own question, it appears that if I use "with" once
for each role it works fine, for example:

{
    package SJQ::Baz;
    use Moo;

    with 'SJQ::Role::Foo';
    with 'SJQ::Role::Bar';

    use namespace::clean;
}

I'm still not clear on why that is necessary though.
