I imagine it probably gets tedious to type '| html' (or html_entity) 
everytime.  Not to mention if he has already wrote tons of pages, it can 
get tedious to go over them and change everything.

Andrew, I don't have a good solution for you.  If you don't have a lot 
of pages and you're just looking for shorthand, you could use a 'hack' 
like this:

$Template::Stash::SCALAR_OPS->{ h } =
   sub {
     my ($scalar) = @_;
     return HTML::Entities::encode($scalar);
   };


Then just do: [% foo.h %]. You might have to do [% foo.h() %] as I 
didn't test that.  Hopefully someone can help you with your original 
question.
