This example compiles fine:

Statement MyNat.one_mul (m : ℕ): 1 * m = m := by
  Branch
    rw [MyNat.one_mul]
  sorry

while this one throws the structural recursion error:

Statement MyNat.one_mul (m : ℕ): 1 * m = m := by
  Branch
    rw [MyNat.one_mul]
    done
  sorry

Should get Branch to throw an error in the first case.
