I think it would be wrong.  An array of floats is an array of floats,
regardless of its alignment.

Well yeah, though you’d still need to come up with an annotation for
that, and I’m not enthusiastic about changing the read syntax for that
purpose.

Now, I think the compiler should support a generic annotation mechanism,
to allow users to specify various things (like ‘declare’ in some
implementations.)  That could be one possible use.
