This is solution for a problem I am currently having with
implementing http://wiki.dlang.org/DIP54 (afair it was also
mentioned by Timon Gehr during old discussion of that DIP)
New proposed semantics ( to catch your attention and get to
read the link ;) ):
template Pack(T...)
{
alias expand = T;
alias opIndex(size_t index) = T[index];
alias opSlice(size_t lower, size_t upper) =
Pack!(T[lower..upper]);
alias opDollar = T.length;
}
// no ambiguity as Pack!(int, int) is not a valid type
// is(element == int)
alias element = Pack!(int, int)[1];
I have nothing against it BUT...
The fact that you need this is a proof that
TemplateArgumentList/TemplateArgumentPack have actually use
outside being template argument list and/or pack.
Your just defeated you whole Q/A on DIP54...
