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

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 foo.pl".  Sample 
(untested) patch attached.

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