Sorry, forgot to actually answer your question. It is preferable 
since it is implied by a simple rule (function attributes go with 
@) rather than rote learning of effectively random historical 
data.

But even if you don't think that's preferable, there's still a 
difference between having a different preference and having one 
preference actually being enforced by the language. In terms of 
coding style, nobody expects a language to enforce a certain 
variable naming convention either.

And this particular change would probably not incur any breakage 
of existing code, unless people happen to be using UDAs with the 
same name as function attribute keywords. It would also, if 
absolute lack of inconsistency is your only determinant, allow 
for this:

@pure @final @nogc func()
@final class G{}

which does fit your stated requirement.
