<pre>The below examples reject:
struct A {
char a;
static constexpr int b = offsetof(A, a);
};
struct A {
char a;
B<offsetof(A, a)> b;
};
And there seem to be no easy work-around.
On stackoverflow people suggest the reinterpret_cast-based
solutions, which are illegal in constexpr too.
Is there anything in standard, that makes this code invalid?</pre>
