Thanks Nick. A voice of sanity. Interestingly I'd decided on the 
argument to the constructor while programming in bed last night.

The change of fashion is very noticeable though - structs for 
everything seems to be a mantra these days. I have started to 
wonder if the two styles could be bridged somewhat if we had the 
default class method type as virtual, and then 'plain' functions 
as well as final ones.
