Type (max (max (max u_1 u_2) (u_3 + 1)) (u_4 + 1))

Typeclass packaging a manifold $M$ with a pointwise tangent space $T_x M$ and the bridge between abstract $2$-forms in Ω 2 and their pointwise bilinear evaluations $\Omega_x$; also records how an almost complex structure lifts to vector fields and interacts with symplectic forms (compatibility, taming, $J^2 = -\mathrm{id}$).
