field is the old name for expand, retained for compatibility, 
it's not recommended. It gives you direct access to the tuple 
inside the Tuple struct, but it's for getting the variable 
values, not their names.

If you want to get the *names* you've chosen for the tuple 
fields, you'll have to use traits of some sort I think.
