A few possibilities discussed around here:
!final
~final
final(false)
@disable final
I've had an epiphany literally a few seconds ago that "final(false)"
has the advantage of being generalizable to "final(bool)" taking any
CTFE-able Boolean.
On occasion I needed a computed qualifier (I think there's code in
Phobos like that) and the only way I could do it was through ugly code
duplication or odd mixin-generated code. Allowing computed
qualifiers/attributes would be a very elegant and general approach, and
plays beautifully into the strength of D and our current investment in
Boolean compile-time predicates.
final(bool) is my preferred solution too.
It certainly is more verbose than 'virtual', but it offers more
possibilities. Also, the pattern is already somewhat established with
align(int).
