I'm a little puzzled by the fact that typesafe variadic functions may be declared to take an associative array, but there seems to be no way of calling the function to take advantage of this.

ie. foo is a valid function when declared as:

    void foo(int[string] bar...)
    {
        import std.stdio;
        bar.writeln;
    }

But the only way to call it seems to be to pass an assoc array as a parameter,

defining a assoc array parameter would make me expect exactly that: that it takes a assoc array as a paramter.


    foo(["a" : 1, "b" : 2]); // Valid

    foo("a", 1, "b", 2); // Not valid

    foo("a" : 1, "b" : 2); // Syntax error

I also can't find any mention of this in the language reference ( http://dlang.org/function.html#variadic ). I assume that the syntax is only valid because it would take an additional specialized language rule to do otherwise, however, it might be neat to actually have this as a feature.

    foo("a" : 1, "b" : 2); // This would be really cool.

whats the benefit of implementing this special case ? you save exactly 2 keystrokes ?
