Set::Intspan 1.06 has been uploaded to PAUSE and is propagating
through the CPAN. In version 1.05, the expression

   Set::IntSpan->new->union("0")

returned the empty set. In version 1.06, it returns the set {0}.

>From the README file:

   Set::IntSpan VERSION 1.06 - Manages sets of integers

   DESCRIPTION
   Set::IntSpan manages sets of integers.  It is optimized for sets that
   have long runs of consecutive integers.  These arise, for example, in
   .newsrc files, which maintain lists of articles:

       alt.foo: 1-21,28,31
       alt.bar: 1-14192,14194,14196-14221

   Sets are stored internally in a run-length coded form.  This provides
   for both compact storage and efficient computation.  In particular,
   set operations can be performed directly on the encoded
   representation.
