proposition: Proposition isaprop_double_functor_hor_comp_laws {C₁ C₂ : category} {D₁ : twosided_disp_cat C₁ C₁} {D₂ : twosided_disp_cat C₂ C₂} {F : C₁ ⟶ C₂} {FF : twosided_disp_functor F F D₁ D₂} {Cm₁ : hor_comp D₁} {Cm₂ : hor_comp D₂} (FC : double_functor_hor_comp_data FF Cm₁ Cm₂) : isaprop (double_functor_hor_comp_laws FC).
proof: Proof. repeat (use impred ; intro). apply isaset_disp_mor. Qed.
