A few possibilities discussed around here:
!final
~final
final(false)
None of those are as nice as 'virtual'. It's not like it's a common
variable name.
@disable final
Nope, already valid.
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.
This is a much bigger change than adding a new storage class, both from the
language and implementation perspectives. How often do you really need this
much power, now that we have attribute inference?
