This is not a good thing. Enums are supposed to denote a 
*closed*, enumerated set of items. It's fine here (but IMO bad 
style) because the author expects there to be user-created values 
casted to Signal passed to functions/templates that expect a 
Signal, but this would wreak havoc on code that was expecting a 
valid enum value (by valid, I mean only one of the predefined 
enum values).
