--- Comment #1 from Andrej Mitrovic <andrej.mitrovich at gmail.com> ---
Changing to a compiler bug:
-----
struct Tuple(T...)
{
T t;
alias t this;
}
auto tuple(T...)(T t)
{
return Tuple!T(t);
}
void main()
{
auto tup = tuple(1);
auto a = tup[0]; // ok
auto b = tup[1]; // Error: no [] operator overload for type Tuple!int
}
