I agree with most of what you say - there should be a way to get access to the history after :trace has finished. Perhaps the right way is just to have a single global trace history.
Please submit a feature request, with a proposal for the user interface, to the GHC bug tracker:
http://hackage.haskell.org/trac/ghc/newticket?type=feature+request
Trace history should not be context/resume specific but global: http://hackage.haskell.org/trac/ghc/ticket/2945 Tracing should be controlled by a global flag (it should not be resume context specific): http://hackage.haskell.org/trac/ghc/ticket/2946 If anybody cares about ghci user interface then he/she should comment on the two tickets since they propose ghci UI changes. I doubt there would be complains about the first ticket but the second one may be more controversial. Thanks, Peter.
