Array of Template instantiations

[Alex via Digitalmars-d-learn]

Hi,

i don't even know if the subject makes any sense :)
What i want to achieve is: instead of making:

>auto v_a = async( &load , queryA );
>auto v_b = async( &load , queryB );
>auto v_c = async( &load , queryC );
( async is a function from vibe and returns a "Future" - see 
http://vibed.org/api/vibe.core.concurrency/async for the async )

i want to something like this:

>WHAT_TYPE[] futures;
>futures ~= async( &load , queryA );
>futures ~= async( &load , queryB );
>futures ~= async( &load , queryC );

And then collect the results somwhere later like:

>foreach(WHAT_TYPE future ; futures)
>{
>  writeln( future.getResult() );
>}

The Problem is, i dont know what type WHAT_TYPE is / i don´t know 
how to build a loopable something of futures.
