Update available-- possibly last before finalization

[David Van Horn <dvanhorn@xxxxxxxxxx>]

Hello,

SRFI 57 has been updated and the latest draft is now available at:

   http://srfi.schemers.org/srfi-57/

The update consists of a small bug fix in the code and a minor reorganization 
of the text.  This will be last revision before finalization (Jan 8) unless 
there are further comments, so please speak up if you have an issue with the 
current draft.

Thanks,
David
