Perhaps a hash of subs would be useful to lift out the conditional tests also, e.g.,

sub template {
    my $e = shift;
    my %actionhandlers = (
            p => sub {...blougat...},
            b => sub {...blimblim...},
            u => sub {...hoohaa...}
            ...
    );               
    return sub {
        ... common stuff ...
        $actionhandlers{$e}->(...args_if_any...);
        ... more stuff ...
    };  
}
