I believe that rnf from the Control.Parallel.Strategies library shipped with GHC 6.6.1 is equivalent to deepSeq, as in:
x `deepSeq` y is equivalent to rnf x `seq` y Isn't it? /g On 9/12/07, Peter Verswyvelen <[EMAIL PROTECTED]> wrote: > Thanks for all the info. > > It's really good news that code coverage is now part of the GHC compiler! > > Any more info on that "deep seq"?
