Yes sorry, I got slightly mixed up there.  But the current text still 
seems clear to me.  You said:

 > It is not clear that "in scope" here really means "in scope and 
exported by module M".

There are two cases:

Either M is the current module, in which case we should not refer 
recursively to the export list in the definition of the export list, or

M is not the current module, in which case the only way that an entity 
could be in scope in the current module is if it was exported by M and 
subsequently imported by the current module, so adding "exported by 
module M" is superfluous.

The current definition is succinct and does the right thing, without 
having to resort to separating the two cases explicitly.  Perhaps it 
could do with a word or two of explanation in the text, though.

Cheers,
