--- Comment #4 from Walter Bright <bugzilla at digitalmars.com> ---
Doing a shrink on the test case:

  alias aliases(a...) = a;

  template sort(alias f, a...) {
    static if (a.length > 0) {
        alias x = f!(a[0]);
        alias sort = a;
    }
    else
        alias sort = a;
  }

  alias SortedItems = sort!(isDependencyOf, String);

  enum isDependencyOf(Item) = Item.DirectDependencies.length == 0;

  struct String {
    alias DirectDependencies = aliases!();
    enum l = SortedItems.length; // no property `length`
  }

If SortedItems is moved last, it compiles successfully.
