Hi,

Interesting idea, but how would you access the fields in a convenient
manner?  Note that nothing beats record access (say, story.title) or even
object method call (story#title) in convenience and readability.

(I guess the convenience aspect could be sorted out with a syntax
extension, but then we're moving into far more complex territory
than I hope is necessary...)

Cheers,
Dario
