This compiles but it should give a CT error since x[4] is out of bounds:
import std.typetuple;
void main()
{
    alias TypeTuple!(int) x;
    static if (is(x[4] == int))
    {
    }
}

This correctly gives the error message, 'int' and 'x[4]' just swapped places:
import std.typetuple;
void main()
{
    alias TypeTuple!(int) x;
    static if (is(int == x[4]))
    {
    }
}

test.d(17): Error: tuple index 4 exceeds 1

Timon Gehr:
Actually it is according to the specification:

"3. is ( Type == TypeSpecialization )
The condition is satisfied if Type is semantically correct and is the same type
as TypeSpecialization."

=> TypeSpecialization is compiled without suppressing errors.
