ParameterStorageClassTuple makes a tuple of values, so

>     alias ParameterStorageClassTuple Stores;    
>
>     static assert(Stores!(t1) == Stores!(t2)); // NG
>     static assert(Stores!T1 == Stores!T2);     // NG

value comparison would work, but

>     static assert(is(Stores!t1 == Stores!t2)); // NG
>     static assert(is(Stores!T1 == Stores!T2)); // NG

type comparison would not work.

>From 2.063, value tuple comparison would work by fixing issue 9873.
