Mason::Plugin::Defer - Defer computing parts of output until the end of the request

    <head>
    <title><% $m->defer(sub { $m->page->title }) %></title>
    % $.Defer {{
    %   my $content = join(", ", @{ $m->page->meta_content });
    <meta name="description" content="<% $content %>">
    % }}
    <body>
    ...

The defer feature allows sections of output to be deferred til the end of the request. You can set up multiple deferred code blocks which will execute and insert themselves into the output stream at request end.

Returns a marker string that is unique and will not appear in normal output. At the end of the request, each marker string is replaced with the output of its associated code. e.g. 

    <title><% $m->defer(sub { $m->page->title }) %></title>

Applies "$m->defer" to the content block. e.g. 

    % $.Defer {{
    %   my $content = join(", ", @{ $m->page->meta_content });
    <meta name="description" content="<% $content %>">
    % }}
