move an argument tuple

Hi everybody,
I'm trying to have a templated function like so:
void func(alias F)(Parameters!F args) {
At some point in func, I want to call F with args:
F(args);
This does not work if one of args is a struct with copying disabled.
That's fine. What I'd like to do is to move it into F:
F( move(args) );
Except that only works if args.length==1. If args.length==2, it thinks
I'm calling the move overload that moves from the first argument to the
second, and then it complains that F cannot be called with void argument.
Things that also don't work:
F( moveAll(args) );
That one accepts two ranges and expects to copy between them.
I guess I can put up a mixin that expands to:
F( move(args[0]), move(args[1]) );
I'd really like a cleaner solution if one is possible.
Thanks,
Shachar
