digitalmars.D - Regressions and git bisect - an app for that?

Speaking of git bisect, a lot of great work has been put into automating things 
with the test suite, and extra things like generating test profile coverage.

It could be an ongoing nice timesaver if a tool could be added to git that, for 
regressions, automatically figured out which PR caused the breakage.

I think that digger, by Vladimir, does that:

Anyone want to apply that to the regression list?

I highly recommend watching the whole video but in case you're in 
a hurry, the Digger part starts here:
