(Golf) showing runs

nop has asked for the wisdom of the Perl Monks concerning the following question:

Can anyone suggest a golfish way to take a sorted array like  @a = (1,2,3,4, 55, 101,102,888) and produce a list of singles and runs (a run is 3 or more conseq integers) like this: 1-4, 55, 101, 102, 888
My solution is ugly and long. Thanks. nop
