FYI,
You are storing the output of it in a variable, specifically in an array variable named output. But then, you are asking the program to display the content of output (which is what you just saved) to the stdout via the print, that's why you see it displayed.
You are right, this might account for the displaying, but thread-o/p said (emphasis by me):

So i suppose he already tested the variables content and came up empty. (Ah, well, you might have a point there ... ;-)) ) It should, even after being printed, hold content, no?
I hope this helps.

mason::filters::standard
Mason::Filters::Standard(3pm) User Contributed Perl Documentation Mason::Filters::Standard(3pm)
NAME
Mason::Filters::Standard - Standard filters
DESCRIPTION
These filters are automatically composed into Mason::Component.
FILTERS
Capture ($ref)
Uses "$m->capture" to capture the content in $ref instead of outputting it.
% $.Capture(my $content) {{
<!-- this will end up in $content -->
% }}
... do something with $content
CompCall ($path, @args...)
Calls the component with path and @args, just as with "$m->scomp", with an additional coderef argument "yield" that can be invoked to
generate the content. Arguments passed to "yield" can be accessed inside the content via @_. This is the replacement for Mason 1's
Components With Content <http://search.cpan.org/perldoc?HTML::Mason::Devel#Component_Calls_with_Content>.
In index.mc:
% $.CompCall ('list_items.mi', items => @items) {{
<li><% $_[0] %></li>
% }}
In list_items.mi:
<%class>
has 'items';
has 'yield';
</%class>
% foreach my $item (@{$.items}) {
<% $.yield->($item) %>
% }
NoBlankLines
Remove lines with only whitespace from content. This
% $.NoBlankLines {{
hello
world
% }}
yields
hello
world
Repeat ($count)
Repeat the content block $count times. Note that the block is re-executed each time, which may result in different content.
<!-- Prints 1 to 5 -->
% my $i = 1;
% $.Repeat(5) {{
<% $i++ %><br>
% }}
Tee ($ref)
Uses "$m->capture" to capture the content in $ref, and also output it.
% $.Tee(my $content) {{
<!-- this will end up in $content and also be output -->
% }}
...
<!-- output content again down here -->
<% $content %>
Trim
Remove whitespace from the beginning and end of the content.
