     95If you know of other relevant language implementations, please add them!

     97[http://www.cse.unsw.edu.au/~benl/papers/thesis/lippmeier-impure-world.pdf thesis] section 2.7 - 2.7.4 pages 115 - 119

     99The Opa language (functional, focused on web development) states that its modules are a special case of records. 
     100 
     101The Agda language [http://wiki.portal.chalmers.se/agda/pmwiki.php?n=ReferenceManual.Records 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)]. 
     102 
     103Other FP languages where I looked for a record implementation but it appeared they have no solution for records with the same fields (my information could be wrong/out-dated) ocaml, oz. However, the O in OCaml is for objects, and objects have structural typing that supports abstraction over fields. 
     104 
     105I 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 [http://www.pllab.riec.tohoku.ac.jp/smlsharp/?FeatureRecordPolymorphism abstraction over fields] as per the overloaded records implementation. 
     106 
     107[http://roy.brianmckenna.org/ Roy], a functional language that targets only javascript, also has structural typing which prevents clashes and allows abstraction over fields.
