Is there any way to pass an unknown number of slices into a function?  I'm trying to do something along the lines of:

void func(T)(T[] args...)
{
    //...
}

That wasn't working, so I tried using another generic type where T was already defined:

void func(U)(U args...)
if(is(U == T[])
{
    //...
}

This didn't work either, so I wanted to know if I was going in the right direction or if I was missing something obvious.

Thanks for the help!

Can you provide more details for "that wasnt working" ? because

  void func(T)(T[] args...)
  {
    writeln(args.length);
  }

  void main()
  {
    int[] a,b;
    func(a[0..$],b[0..$]);
  }

works, so there must be a missing detail.
Maybe each slice has different type ?

in some cases T[][]... will work better too. depends on the details here....

I think the problem is that typesafe variadics bind to arrays as well as individual parameters. So func(a[0 .. $]) for instance would resolve as func!int instead of the desired func!(int[]).

The answer might be:

func(T)(T[][] args...)

as Adam says.
