+The `@[to_additive]` and `@[to_dual]` attributes are pieces of automation
+that respectively generate additive versions of algebraic multiplicative
+statements and dualised versions of order/category theoretic statements.
+Where applicable, these attributes should be used
+over writing the second statement by hand.

+-- `to_additive` can't be used here because `ℝ` can't be additivised.
