Yes, if you "use Encode" you are done for, to be sure. Does it
happen even if you don't do that?
It's a darn shame that there are so many runtime requires. That is a
constant potential for file compromise compromising security, and it
ups the stakes of code injections or page compromises. That is
probably not a huge area at the margin in security, but still. What's
worse is the potential for user error to compromise their files and
I do recognize that it isn't the be-all and end-all of security,
but it makes it easier to do things and be safe.
That being said, PerlAlwaysGlobal and the Alias call I mentioned should
bring things in line...
