This assumption was wrong.  What really happens is that there's a constructor
marked as `inferRetType`.  It's body is empty so it is inferred `void`.  Then
an automatic `return this` statement is appended to the body (because it
isCtorDeclaration), and an assert is triggered because the return type is
`void`.
