Let x0 of type ι be given.
Let x1 of type ι be given.
Let x2 of type (ι → ο) → ο be given.
Let x3 of type ι → ο be given.
Let x4 of type ι be given.
Let x5 of type ι be given.
Assume H0:
x0 = 98165.. x1 x2 x3 x4 x5.
Apply H0 with
λ x6 x7 . x1 = f482f.. x7 4a7ef...
Let x6 of type ι → ι → ο be given.
