You can just add it to your TT configuration, which is probably set in 
your view class.  It's the "PLUGINS" option to Template->new().

Or, again, you could do it in your view class.

That's what I'm saying: it does not need to be called Template::Plugin:: 
or inherit from any Template module in order to use it this way.  Check 
out the TT docs for the USE directive and the LOAD_PERL and PLUGIN_BASE 
config options for more details.
