Topic: toDual/ofDual alignment

/-- `toDual` is the identity function to the `OrderDual` of a linear order. -/
def toDual : α ≃ αᵒᵈ :=
Equiv.refl _
/-- `ofDual` is the identity function from the `OrderDual` of a linear order. -/
def ofDual : αᵒᵈ ≃ α :=
Equiv.refl _
should these not have #align
statements?

Yes. I was wondering why they never seemed to work

Done in mathlib4#1366

I hadn't added them because this file was ported before the "mathport outputs an align statement for every decl" was turned on. And these two decls did auto align by mathport as it is

Aha, thanks for the explanation
