Maybe.. but I have a feeling this would break code. E.g.:

void callback(scoped Event event) { }
auto event = scoped!Event(...);
callback(event);  // implicit, but OK

Now if the 'scope' storage class actually did something useful in a parameter
list, then the above would also be safe.

I suppose you want this to become:
callback(cast(Event)event);

I could live with that, but I'm not sure if any code for other people would
break. I hear relatively little about people using scoped (most people seem to
use emplace instead).
