The post-solution commentary suggests
intro h
rw [add_succ, add_succ, add_zero] at h
repeat apply succ_inj at h
apply zero_ne_succ at h
exact h
but there is no repeat
in the tactic list:

I believe this one is by design of the author (aka Kevin Buzzard), similar to how nth_rewrite
also does not appear in the list but only in the documentation of rw
.
But thanks for all the comments about typos, etc. I will look through them and merge them on the authors behalf next week!

@kbuzzard that's actually a point here. So far we have nth_rewrite
/nth_rw
and repeat rw
as "part" of the rw
tactic and doc.
But repeat apply
isn't really explained.
Should repeat
maybe get it's own doc after all?
