View on Github →chore(Algebra.Quaternion): scope simp theorems with weak keys (#21029)
The discrimination keys of these do not reference QuaternionAlgebra so can apply broadly with simp. There is already essential notation scoped to this namespace so open scoped QuaternionAlgebra should not burden the user any more than it does currently.
