Currently we can do:
<result property ="FirstName" column="FIRST_NAME" />
I'd like to add...
<result field ="_firstName" column="FIRST_NAME"/> <!-- I'm not advocating underscores -->
...and...
<result column="FIRST_NAME" />
The latter (which lacks both property and field attributes) would be a constructor parameter. It would have to follow some rules:
1) Constructor results must come first in the result map defn.
2) Constructor results must be in the same order as the parameters of the constructor.
I think constructor and field support would be awesome in both the .NET and Java versions.
Thoughts?

Yes, actually.
I'd prefer to make some properties read only, having them set only in
the constructor. I'd use this for simple, immutable, value types, as
well as for some mandatory properties on mutable objects.
