It's hidden away in the deep, dark recesses of Template::Manual::Variables 

       If you want to create or update truly global variables
       then you can use the 'global' namespace.  This is a hash
       array automatically created in the top-level namespace
       which all templates, localised or otherwise see the same
       reference to.  Changes made to variables within this hash
       are visible across all templates.

           [% global.version = 123 %]
