@nogcclass? (Way to solve bugs regarding destroy)

[12345swordy]

ATM the destroy function can't be called in a @nogc context, 
severely handicap the use of the @nogc attribute. Can we add a 
@nogcclass attribute for classes or at the very least have @nogc 
attribute apply stricter rules when applying to an entire class?
Rules such as checking to see if every member variable and 
function is @nogc recursively until the base class that it's 
inherited from.
