patch applied (ghc): Changing internal data structures used by

No worries Simon!
To test the -fhpc you use the hpc test suite - still in vaporware,
but will be installed *before* 6.8 RC1.
What I do is run a ~12 module program for coverage, and look at the
output for sanity right now.
Inside the Coverage.hs changes, the scoping was broken. The state was
escaping, and local names
were being marked as x.y.z.a.b.c.... - basically every name in *any*
scope. Opps - but with no test
suite I can not complain. I changed the monad to use an environment
for the scope, forcing
the scope to be accurate by design during recursive descent.
Otherwise, we have coverage working fine right now. I needed to fix a
problem with cases round
errors, but this is a corner case, and ticks are preserved now.
What is the state of the GHCi debugger? What can I do to help? Where
would I put documentation
for hpc in the GHC manual?
What is a good way to package up the hpc tools for GHC users? Cabal?
How do we handle Cabal built library packages vs Cabal built tools
