View on Github →chore(Order/Lattice): Resolve porting notes (#11034)
- The
dsimp
issue has been resolved. - I knew that the lemmas provable by
simp
were provable bysimp
in Lean 3, but the simp nf linter was more lax. Now there's definitely no need to tag them. ematch
is not coming back (and was already completely unused for years in Lean 3).- Unification has changed in Lean 4, so it's really unsurprising that we need to provide an extra argument to
sup_ind
. It's not expectable that this will ever change, neither is it necessary. - Dot notation on
Function.update
is still broken. This is the last remaining porting note.
