[swift-users] Dimensional analysis

Another feature I would like would be a dimensions wrapper for an array. So
that I can mark all values in the array as having the same units, rather
than mark each individual element as having a particular unit.

It is conceivable that wrapping each element, both performance and memory
wise, is OK depending on implementation. However my experience with
Mathematica's Quantity is that wrapping each element is a significant
overhead. Therefore I would like a dimensioned array.

As an aside. It might be a lot easier to write an array wrapper when we get
Conditional Conformance To Protocols with the improved generics slated for
Swift 4.1. Therefore it might be worth waiting until 4.1. before attempting
a dimensioned array.
