Description
In the highlighted end of the following quote, the subject seems to be swapped with the predicative:
Function types occupy the smallest universe that can contain both the argument type and the return type. This means that Nat → Nat is a Type, Type → Type is a Type 1, and Type 3 is a Type 1 → Type 2.
Shouldn't it be instead: Type 1 → Type 2 is a Type 3 ?
