The Agda language [ generates a module (name space) for each record and also allows a record, like any module to be placed into the global scope by the programmer (opened in Agada terms)](http://wiki.portal.chalmers.se/agda/pmwiki.php?n=ReferenceManual.Records).

I couldn't find great specific information on record implementation ML variants. Best I can tell, SML does not allow records in the same module with the same field. Records from other modules require name-spacing or must be opened up similar to Agda. SML\# supports [ record field polymorphism](http://www.pllab.riec.tohoku.ac.jp/smlsharp/?FeatureRecordPolymorphism) as per the overloaded records implementation.

[ Roy](http://roy.brianmckenna.org/), a functional language that targets javascript, does have record field polymorphism (which makes a lot of sense in that context).
