according to

    http://scan.coverity.com

perl is currently at 0.151 and Python 2.5 trunk is at 0.055.  looks like the
perlheads decided to write press releases rather than fixing their core...

(given how Coverity works, the "raw" unreviewed defect density figure is
relatively useless, and anyone using that for marketing is a complete idiot.
I've no time to read the article, but I do hope it's not some Coverity guy
you've quoted...)

(also note that most true Python bugs found by Coverity are of the "may
leak or misbehave under extreme pressure, in the unlikely event that you
get here under such circumstances...")
