I see no reason to diverge from that.
Welö, except for the fact that "any kind of variable" is not
well-defined for a language that supports user-defined alignment
restrictions:
Correct me if I'm wrong, but my understanding is that align(N) on a
member only specifies the alignment *within the struct*, i.e. the member
offsets. There's no guarantee that the Foo object itself will be aligned
to 8192. It's not really memory alignment.
Yah, something like that. I found align(NNN) underspecified and
underpowered for my work with allocators. As a simple matter, NNN must
be a literal, not a compile-time expression. You can't even write e.g.
align(size_t.alignof), which is fairly basic.
