Aaand for contrast, if we had __ident and static foreach:
final class Finalize(T) : T
{
this(T...)(T args) if(is(typeof(new T(args)))) { super(args); }
static foreach(member; __traits(allMembers, T))
static if(__traits(isVirtualFunction, __traits(getMember, T,
member)) && !__traits(isFinalFunction, __traits(getMember, T,
member)))
override ReturnType!(__traits(getMember, T, member))
__ident(member)(ParameterTypeTuple!(__traits(getMember, T, member)
args)
{ return super.__ident(member)(args); }
}
Err this sort of __ident is implemented by my patch against allMembers.
It's arranged as:
[ "membername", membersymbol, "member2name", membersymbol]
that is
__traits(allMembers, ClassSym)[1](3,4) would call the second member of
ClassSym with args (3,4)
