Sorry Rob,

Took me a while to spot this email. It's entirely Hat related,

  FFL_INVIS
     means treat this function as though it didn't exist 

     from a tracing point of view.

  FFL_LAMBDA
     means this is a lambda function so don't try to
     trace it's name or anything.

  FFL_PRIM_APPLY
     means this is the special inbuilt apply function that is so special
     you can't even write it in Haskell. So please trace it specially.

Thanks

Tom
