Enums in D may be scoped. There is nothing that prevents you from 
declaring your enum thus:

enum { protected_, private_, none }

making the shorter version perfectly legal.

mixin(signal!(string, int)("valueChanged", protected_));

Your concern about extra typing by always needing to specify the scope 
is thus unwarranted.
