$cgi->Vars separates multiple values with a null byte, thus increasing
the risk of the person using this being vulnerable to a null-byte hack.
I would only use this if you're migrating from the Perl 4 cgi-lib.pl.
Also. having to do "@foo = split "\0",$params->{foo};" is not fun and
it's easy to get wrong.
If someone needs multiple values, they should just take advantage of
list context:
my $foo = $cgi->param('foo'); # single value
# versus
my @foo = $cgi->param('foo'); # multiple values
