Is it possible to compare at compile time an element from a TypeTuple with another type?

This code fails:

    alias T = Tuple!(int, bool);
    static assert(is(T[0] == int));

Error: static assert (is(Tuple!(int, bool)[0] == int)) is false

Tudor

alias T = TypeTuple!(int, bool);
static assert(is(T[0] == int));

or

alias T = Tuple!(int, bool);
static assert(is(typeof(T.expand)[0] == int));
