eg:
while ( my ( $key , $val ) = each %hash ) {
my $weBe = weAreSomeWhat($val) ;
if ( $weBe eq "ARRAY" ) {
dealwithArray($val);
}elseif ( $weBe eq "HASH" ) {
....
}....
}
hence we want to resolve what this
sub weAreSomeWhat {
}
would have between the curly braces....

the other strategy is to feel more at home with doing
the OO approach and the full encapsulation of your data
cf: perldoc perlboot, perloot, perlootc
this way you put your 'sets and gets' in such a way
that you have hidden from everyone how exactly the
my $thingie = FOO::BAR->new(@configMe);
did, and that if they wish to do
my $data = $thingie->getKey2();
your mileage will vary.
