struct S { char[] str; }
void main ()
{
auto s1 = S(cast(char[])"abc");
auto s2 = S(cast(char[])"Xbc");
// indirect members in structs are compared by value
assert (s1 != s2); // ok, structs are compared not equal
s2.str[0] = 'a';
assert (s1 == s2); // ok, structs are compared equal
// not so in AA
auto aa = [s1 : 1];
auto s1aa = s1 in aa;
assert (s1aa);
auto s2aa = s2 in aa;
assert (s2aa); // fails, but should pass
// s2 should be found in aa the same way as s1
