> I was wondering if you had considered/had comments an alternative approach where you declare an ordinary new value type which meets certain rules and ‘wraps’ the existing type, then define new syntax/features in Swift for having the wrapper (or possibly even multiple levels of wrappers) be more transparent for use.

You might want to take a look at the first version of the proposal. It defined behaviors using existing constructs with certain conventions, and most posters argued that it was a bit of a mess and needed syntax to clarify what was happening.
