No, it looks like it's just ($cap, $list) where $cap and $list are 
arguments to _ca_process() passed from do_lca().  The value of $cap passed 
into do_lca is split on '/'

  my $cap = [split '/', $in{'cap'}];

The value of $list is just appended to the arguments via unshift

I agree it's pretty horrible, looks like the code hasn't had a lot of 
attention paid to it lately.

Same problem, since it's the same code.

How many people other than use actually use this interface?  It wouldn't 
be hard to de-uglify if there isn't a problem of backward compatibility.
