You can ommit the template argument list parenteses only for 
single symbols.


Starting with the full syntax:

  Array!(Item!(T))

Since Item!(T) uses a single symbol, T, you can remove the 
parenteses from that one:


  Array!(Item!T)

The following compiles:

import std.container.array;

struct Item(T) {
}

void main() {
alias T = int;
auto a = Array!(Item!T)();
}

yup that was the issue.
