| @[simp] theorem getElem_take (a : Vector α n) (m : Nat) (hi : i < min n m) : |
There was a problem hiding this comment.
This should be i < min m n not i < min n m. The latter works, but because the size of Vector.take v m is min m n, using i < min n m makes it less useful in automation (because simp can't necessarily find the proof).

This PR adds `GetElem` lemmas for the basic `Vector` operations. The `Vector` API is still very sparse, but I'm hoping to infill rapidly.
