Ok, cool. I'll have a look at using Neil's code and see if it needs
any updating or if something is missing.

Thanks for mentioning this! I don't have any concrete plans to change
that at the moment, but I was thinking that in the future it'd be nice
if the results were, e.g., a simple csv file, instead of a log
containing all the stdout/stderr (i.e., it currently contains the
results, any warnings from GHC, output from `Debug.Trace.trace`,
Anyway, that's probably further down the road, so before doing
anything, I'll likely send an email to ghc-devs so that we can discuss
