Description

The fact that Foo.out true is printed as true.out is confusing, since that looks like Bool.out true.

structure Foo : Type where
  out : Nat

/-
application type mismatch
  true.out
argument
  true
has type
  Bool : Type
but is expected to have type
  Foo : Type
-/
#check @Foo.out true

Expected behavior: true.out prints as Foo.out true
