Unable to create `TestScheduler.Configuration` about entwine

[tcldr]

Hi Bryan,

Does the following not work for you?

var config = TestScheduler.Configuration.default
config.cancelled = 1000

That works, but then I'm modifying the configuration for all tests instead of just one individual test. In this case, I only want to change it for one test.

[tcldr]

As TestScheduler.Configuration has value semantics (i.e. a basic struct) assigning it to a new var creates a copy of the configuration – the default isn't modified and in fact, can't be, as it's a static let property with value semantics.

I always forget that basic structs use value semantics. Sorry for the momentary lapse in intelligence. The code above works just fine!
