RE: [GHC] #1712: unknown symbol “glutGet”

[Simon Peyton-Jones]

| I need a suitable record system for Grapefruit (which supports defaulting for
| input record fields and leaving out fields in output records).  Since I
| failed to implement one based on functional dependencies in the first place,
| I switched to type families.  They make certain things possible which seem to
| be impossible with functional dependencies.  That’s why I just hope for the
| best concerning type family support and don’t switch back to functional
| dependencies at the moment.

As Manuel says we'd definitely be interested in this example.

| When is GHC 6.10 expected to be released?

We don't have a current plan about timescale.  Certainly not until the type function story has settled down.  Months for sure.
