Maybe it makes sense to use consistent variable naming within Polly.Specs ?
Changing these variations var tokenSource = new CancellationTokenSource(), var cts = new CancellationTokenSource(), var cancellationSource = new CancellationTokenSource()
to
var cancellationTokenSource = new CancellationTokenSource()

I considered that, but some also have custom names and it was just a quick drive-by change while I was preparing the next release, so I'm going to leave them as they are for the time being.
