Summary:
--------
No rationale is given for having the library (r6rs enum) in the report.  Unless 
there is a compelling rationale, it is suggested that the library be dropped.
Description:
------------
In the absence of a rationale, it is difficult to judge whether this library is 
really essential.  In contrast to most of the other libraries included in the 
report,
   - I do not think enumerations were part of the r6rs mandate.
   - there does not seem to be a general feeling in the community that
     enumerations are essential and should be standardized.
   - it is unclear what sets enumerations apart from a whole plethora
     of excluded possible libraries that may have been as useful or more useful.
   - there is no widespread prior usage experience of enumerations.
   - it seems to be an ad hoc encapsulation of accidental functionality
     used in the implementation of other libraries.
I do not personally know a sufficiently strong reason to include 
this library in the report.  I do not deny that enumerations may 
be useful, but since the report is already regarded by many as too large,
perhaps this library might be profitably excised.
Suggestion:
-----------
Perhaps drop this library.  Alternatively, it may be helpful to provide a 
compelling rationale for including it.
