Comment (by dfeuer):

 What we really want, I think, is for users to be able to specify
 (globally, and perhaps also for individual loaded files) whether they want
 extra-aggressive recompilation avoidance. That would include optimization
 level and HPC (is that covered under the `prof` bit?), and perhaps other
 profiling options.
