Will implicit parameters survive?

I don't have any active plans to remove implicit parameters.  I think they are not heavily used, but for those that do use them they seem to be quite helpful, and (important for me) their effect on the compiler is quite localised, so they cause little trouble.

Still, I'm always interested to know how much interest there is in particular features.  Maybe we should do a new GHC survey!

| Hello,
| what are the plans for implicit parameters?  Will GHC continue to support them
| or could it be that they will be removed at some time?
| I think that implicit parameters can be very useful for implementing global
| variables as described in <http://www.cs.chalmers.se/~rjmh/Globals.ps>.
| Surprisingly, the interest in implicit parameters seems to be rather low as
| the GHC survey from 2005 suggests.  Despite this, I’d propose that support
| for implicit parameters continues.  But what do the GHC developers think?
| Best wishes,
| Wolfgang
