Why, in ghc-6.8.2, it works in my Dumatel program:
let
...
(pairsPassed, pairsRest) =
{-# SCC "(pairsPassed, pairsRest)" #-}
span (not . isFalseTerm . fst)
[(dj', c) |
sb <- testingSubsts,
let (_, dj', _reduction, c) =
reduceDisjunct emptyUMRMemo jump calcExt [] $
substitute sb dj]
...
in ...
The SCC point is named so that it is easy to recall where in the source
this point is set. Here it is better that denoting, say "103".
Am I missing something?
