Well, that's the issue... I do need the CGI module.  (The above code
was just to demonstrate the error.)

The Net::Braintree module that I'm using for the payment module uses CGI.

It looks like I could hack the Net::Braintree module to use the
interchange $CGI values, but I would rather keep the code vanilla so I
can upgrade in the future, if necessary.

I'm not a perl expert, so maybe I'm grasping at straws here, but it is
a namespace issue?  I grepped through the source for CGI, and I found
this in Server.pm in the "reset_vars" subroutine:

package CGI;
reset 'A-Z';
reset 'a-z';
