Comments and end annotations

In reading some library code recently, I got confused because I  
didn't realize that some code was commented out, and that some other  
code was part of an object declaration.  So I wonder if what others  
think about the following:

1. When code within comments is rendered as ordinary Fortress code,  
it is slightly indented with a continuous vertical line at the left  
margin.  If there are multiple levels of nesting such commented-out  
code, then there should be one such line for each level of nesting.   
(Basically mimicking quoting in many mail handlers.)  This affects  
only the rendering of Fortress comments, not the syntax or semantics  
of Fortress code.

2. After the closing "end" of a multiline trait or object  
declaration, or a component or api declaration, it is permissible  
(but not required) to write the name of the trait/object/api/ 
component being declared.  Such a name must appear on the same line  
as the end, and it is a static error if it does not match the name  
declared.  (The static parameter list is not considered part of the  
name for this, or any other, purpose.)  For example,

object O
end O

trait A[\X\]
end A

(* the following is a static error *)
trait T
end x
