The OverloadedRecordFields extension for GHC will allow multiple record datatypes to share the same field names, and make it possible for type information to disambiguate them. For more information, see:

Open Tickets:

Implement TDNR
Interaction between ORF and record pattern synonyms needs to be resolved.
Unable to infer type when using DuplicateRecordFields
Allow applying type to label
Allow labels starting with uppercase with OverloadedLabels

Closed Tickets:

DuplicateRecordFields + TemplateHaskell
Fixity of field-deconstructors incorrect
Infix declarations for record fields with DuplicateRecordFields are broken
Interaction between ORF and record pattern synonyms needs to be resolved.
Auto complete in ghci shows $sel:function:Type for DuplicateRecordFields fields
Regression using NamedFieldPuns with qualified field names
DuplicateRecordFields appears not to work in GHCi
RebindableSyntax and OverloadedLabels
UnboxedTuple makes overloaded labels fail to parse
unused-top-binds wrongly warns about underscore-prefixed field names when DuplicateRecordFields enabled
Compilation fails with a panic: get_op runContT

Add ORF to the ticket's keywords to include it in these lists.



The extension was implemented in 2013 as a Google Summer of Code project, by Adam Gundry under the mentorship of Simon Peyton Jones.
