The B in the params and the B in the pattern are not the same B

Commit: ccaa7a0

open data Unit : Type | unit

open struct Wrapped (A : Type) : Type

def test {B : Type} Unit : Wrapped B -> Unit
  | unit => \(x : Wrapped B) => unit

All these changes would fix the error:

def test {B : Type} Unit : Wrapped B -> Unit
  | {B}, unit => \(x : Wrapped B) => unit

def test {B : Type} Unit : Wrapped B -> Unit
  | unit => \x => unit

def test {B : Type} Unit : Wrapped B -> Unit
  => \(x : Wrapped B) => unit

Oh, I understand now.

Yes, I mean to do the replacement in the whole function body. If we were to disallow generalized variables used in bodies, we would have to look through the body for any used generalized variables to provide better error reporting anyway (I think).

I know how to fix this.
