Bug 582 – Cannot slice mixed tuples

template Tuple(E ...) { alias E Tuple; } alias Tuple!(float, float, 3) TP; alias TP[0..length-1] TQ; DMD gives following error when compiling the above: err.d(4): tuple E is used as a type err.d(4): Error: can only slice tuple types, not void This doesn't exactly contradict the spec (AFAIK), which is a little vague about using tuples outside of templates, but it does directly contradict the essay at http://www.digitalmars.com/d/tuple.html, which in fact uses this as an example.

See also bug 586, which refers to the same problem with indexing tuples.
