Will implicit parameters survive?

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
