I am trying to fill out a general nested structure from flat and orderless name=value pairs of CGI params. I want the name to be split on '.' and used as multilevel hash keys. The values are scalars or arrays: 
my $cgi = CGI->new( 'a.b.c=3&a.b.c=4&x.y=4' );
# convert somehow to:
my $args = { a => { b => { c => [3,4] }, 
             x => { y => 4}               
           };

I realize that adding a=1 to the above list would cause problems. As long as I the user can't cause a "not a HASH ref" error I'm not too concerned at this stage.

I wrote some cruddy code for this but couldn't think of a nice way to access and assign to the nested hash. Any suggestions?

PS. No $;='.'
