This is the closest we got so far to the intended result.
If there was a way to enter attributes without quotes, it would be
almost identical.
Anyway, I wonder if the code comparison in www.rubuclr.com between the
c# and ruby code is fair...
As far as I know, classes and structs are not the same thing.
In the case of that ruby example, can someone add methods later?
