And Haskell has that too:

data Field1 deriving Typeable; field1 = proxy::Proxy Field1

Haskell's records are a bit annoying, and type-classes often group together
too many methods, which means you make early decisions about future unknown
requirements, and IMO you always get it wrong :-)
After having read an email in the cafe about the Noop language Self
language, I realized that
Short answer: There is no good way of doing what you want.
This is actually one of my biggest annoyances with haskell (right up there
with disallowing infinite types). They are many techniques that work better
or worse depending on the application, but non are very satisfactory IMO.
