[cgiapp] runmode return scalar reference ?

["James.Q.L" <suppressed>]

hi,

poking through C::A src code and i noticed that one can return a scalar reference as output from a
runmode. as indicated by the followying lines from run subroutine.

# Support scalar-ref for body return
my $bodyref = (ref($body) eq 'SCALAR') ? $body : \$body;
....
# Build up total output
my $output  = $headers.$$bodyref;
.....
return $output;

C::A doc doesn't mention it and i have never seen ppl doing stuff like 

sub my_runmode {
    return \$tt->process(...);
}

but it seems to be a good thing to do,especially in mod_perl. my question would be.. is this a
well-known behaviour?

thanks,

James.
