template getParameters( T, alias P ) {
    static if ( is( T t == P!U, U... ) ) {
        alias U getParameters;
    } else {
        static assert( false );
    }
}

void main( ) {
    alias getParameters!( Tuple!(int, string), Tuple ) args;
}

This asserts. Replace T t == P!U, U... with T t == Tuple!U, U..., and it works.
(but of course then the intended functionality does not work)
