[Catalyst] How to get modified form params back into form

[RA Jones]

My form passes a series of data values as a :: delimited string in a 
select called 'match':

<select name='match'>
   <option>LastName::FirstName::DoB::etc</option>
   # more combinations

and I want to populate the $c->detach template fields with the selected 
values. This works if I do:

my ($last_name, $first_name, $dob, $etc)
   = split '::', $c->req->param('match');
	
$c->request->param(last_name => $last_name);
$c->request->param(first_name => $first_name);
$c->request->param(dob => $dob); # etc

and it populates the template with the appropriate values, but it seems 
a bit messy as I'm attributing values to request parameters that were 
not actually there in the first place - is there a better way?
