template Tuple(A...)
{
    alias A Tuple;
}

template Foo()
{
    mixin ("alias Tuple!(1) tuple;");

    static if (tuple[0] == 1)
    {
    }
}

alias Foo!() foo;

test.d(13): Error: undefined identifier tuple


Add an intermediate alias to work around it:
----
template Foo()
{
    mixin ("alias Tuple!(1) tuple;");

    alias tuple betterTuple;    
    static if (betterTuple[0] == 1)
    {
    }
}
