be_a() and --verbose

[emiltin]

When using is_a() or be == to verify that an object is a specific class, for example:

expect(collector.messages).to be_a(Array)
expect(collector.messages).to be == Array

Then the --verbose output shows the entire object:

I find this a bit noisy (especially for arrays), as the expectation is really only about the class. I think something this like would be enough:

expect Array to
be is_a? Array
