Linear web programming in Mason?

Hi.  Does anyone know if there were any attempts or discussion to bring Mason
toward the "linear web programming model", ala Seaside
(http://beta4.com/seaside2/) or Borges (http://borges.rubyforge.org/)?

This is so one can write components that resembles sequential programs
instead of state machines.  A short example follows:

%# Counter.mas:
    <& /header &>
    <h1>Current Counter: <% $count %></h1>
    <&|/button, $m->run_method('Incr') &>++</&>
    <&|/button, $m->run_method('Decr') &>--</&>
    <%INIT>
    my $count = 0;
    </%INIT>
    <%METHOD Incr>
    % $count++;
    </%METHOD>
    <%METHOD Decr>
    % if ($count == 0) {
    %   # to the user, the next line brings up a new page...
    %	my $ok = $m->run_comp('Confirm.mas', Text => 'Go negative?');
    %   # ...after the user clicks "Yes"/"No" we are back here!
    %   return if !$ok;
    % }
    % $count--;
    </%METHOD>

%# Confirm.mas:
    <& /header &>
    <p>Please confirm: <b><% $Text %></b></p>
    <&|/button, $m->yield(1) &>Yes</&>
    <&|/button, $m->yield(0) &>No</&>
    <%ARGS>
    $Text
    </%ARGS>

I understand the subtleties involved (serializing Coro::Cont state for
lexical variables; make continuation-passing-style $m facades; separate
backtrackable methods with nonbacktrackable ones); I merely wish to
check if were prior arts or discussions about this in the Mason/Perl
space, and if this is an obviously insane approach to try with Mason.

Thanks,
