Possibly but please check before using because I think 'invariant' 
requires presence of member functions:

My first thought was why not use a slice anyway?

Worth noting that static arrays are value types. Also, they all have 
different types from each other and have the potential to cause template 
bloat.

Off-topic, most D programmers use struct unless they need class.

Makes sense to me.
