    alias TypeTuple!(char, int) TT;

These declarations must be IDENTICAL:

    void foo(TT);
    void foo(char, int);

    struct S { TT t; }
    struct S { char t1; int t2; }

This means that if you have an aggregate that is a tuple (and tuples 
are, of course, aggregates) you have an aggregate that needs one 
alignment in one context, and another alignment in another. It doesn't work.
