It is almost expected of me, that I would have to point to Why is 'our' good? for an explanation of what I don't like about our, and Trivial style ideas giving my alternate answer to the above issue. In the above example my standard would look like this:

package Xyz;

use Exporter;
@ISA = 'Exporter';
@EXPORT_OK = qw [
  FunctionAlpha  FunctionBravo  FunctionCharlie  FunctionEcho
  $calarDelta  $calarFoxtrot
];

use strict;

# etc

Note that I dropped @EXPORT. Read the documentation for Exporter for an explanation of why.

Sometimes I will move strict up and use vars to declare the globals. Usually not.
