I wish there was a more efficient way to do this.
this is also a possible application of my approach, by providing a „I want this data structure to be fully evaluated now, please tell me how it currently looks, i.e. where in the data structure still thunks lie hidden.“ Do you have a nice, striking example where using your approach (using deepseq and comparing efficiency) you could make a difference, and where a tool as described above would make the analysis much easier?
