Setting a hard limit on slice size, is this possible?

I've never actually tried this myself, but have you looked into the
`align` keyword in the D spec?  I'm not 100% sure whether it can be
applied to static arrays (or arrays in general) but it might be worth a
look.

One thing that might help you is if you had a struct with the
appropriate align(...) declaration that wraps around your array
elements. Pretty sure that would guarantee the alignment of array
elements, which in turn should guarantee alignment of the array as a
whole.
