[Haskell-cafe] Hugs Trex for GHC / JHC / UHC / ... ?

I briefly read about Hugs record system Trex, and at first sight this was really nice! I know this question was asked a long time ago already, but are there any plans to add this extension to GHC? What about the other compilers, like JHC, UHC, etc? Is it possible to emulate Trex (lots of other record systems exist), *and* get the same easy to understand errors? What were the problems with Trex (if any)? Thanks, Peter Verswyvelen
