[Haskell-cafe] Substitute for records?

Currently i'm working, together with a friend, on an abstraction (sort
of) of HaskellDB for a school-project.
Basically we are generating haskell-modules similar to those generated
by DBDirect in HaskellDB together with some helpers for the most common
queries you'd want to run.
HaskellDB has its own record system (HDBRec) and a HaskellDB-query also
returns such a record. The accessor-functions for these records can
later be found in DatabaseName.TableName.ColumnName.column. These should
be imported qualified to avoid name clashes.
This is some example code:
students <- School.Students.all db
mapM_ printStudentId students
printStudentId rec = print $ rec!School.Students.Id.column
The main problem for me here is this part:
where i would rather just write
This isn't possible and the other way is just too messy for my taste. It
simply isn't the easy and nice syntax i had hoped for when we started to
Are there any other nice substitutes for HDBRec or normal haskell
records that i could use that doesn't make name clashes an issue?
