[New-bugs-announce] [issue4098] surprised by default list parameter

New submission from Torsten Rottmann <trott at meditec-gmbh.com>:

The attached file produced the following result:

trott$ python2.5 p6.py

I expected both times the empty list since the print
statement prints just a defaulted parameter ("e") which
was defaulted to an empty list literal ("[]") and never set
by supplying an actual class parameter.

The object property "entries" appears to be shared by
both instances. Why?
