[Templates] trying to leave HTML::Mason for TT2

Yep, that's probably the best way to do it at present.  In this case, 
you're processing the BLOCK and storing the output in 'content_1'.
You can also define a MACRO which will evaluate the BLOCK when it is
inserted (i.e. lazy evaluation).

e.g.

[% BLOCK site %]           
   [% INCLUDE header 
      title="My Cool Web Site: $section" 
   %]
   [% x FOREACH x = content %]
   [% INCLUDE footer %]
[% END %]

[% MACRO content_1 BLOCK %] ... [% END %]
[% MACRO content_2 INCLUDE something FOREACH x = xstuff %]

[% INCLUDE site 
   section = 'Section X'
   content = [ content_1, content_2 ]
%]

No, not yet.  I think there's definately some mileage in being able to 
control the process flow by means of a 'super' call, or something 
similar.  I need to go and dig out some functional programming papers
because I'm sure I've seen something to do with co-routines that might 
be relevant here.
