Is there any chance that link could supply some HTTP headers as well as 
the body?  It's rather confusing to poor little Safari.  Firefox manages 
to display it ok, but that could just be luck.  :-)

It looks like a really good idea.  As to choosing the package name, the 
easy way is probably to use an environment variable.  You could also use 
import(), so you could say "perl -d:Memory=My::Package".  Sample 
(untested) patch attached.

I do actually happen to quite like the name...
