If you have a struct that does not define opEquals, but which contains a member
that defines opEquals, that member's opEquals is called when comparing the
struct.

However, arrays are still bitwise compared.  Example:

struct String
{
    char[] data;
}

void main ()
{
    auto foo = String("foo".dup);
    auto bar = String("foo".dup);

    assert(bar.data == foo.data);
    assert(bar == foo, "oops structs aren't equal");
}

results in the second assert failing.
