Mathlib.CategoryTheory.Monoidal.Limits.HasLimits

Compatibility lemmas for limits and colimits in a monoidal category #

For numerous simp lemmas of the form f ≫ g = h, we add accompanying simp lemmas of the form Q ◁ f ≫ Q ◁ g = Q ◁ h and f ▷ Q ≫ g ▷ Q = h ▷ Q. This file and Mathlib.CategoryTheory.Monoidal.Limits.Shapes.Pullback are needed to define a monoidal category structure in Mathlib.CategoryTheory.Monoidal.Arrow.

TODO #

An attribute should be developed to automatically generate lemmas of this form.
