What I want is: I'm working on a module to allow me create objects on the fly (I know there are a bunch of cpan modules that does exactly the same and better, but I was wondering how would that be, and also considered that a good learning experience) The point is that I'm using something like this (On my main class): 
sub AUTOLOAD {
    my $_call = our $AUTOLOAD;
    $_call =~ s/.*:://;
    my $self = shift;
    my $param = shift;
    ...
    $self->{$_call} = $_param || return $self->{$_call};
}

So far, so good. But the problem is, that at some point, when I initialize a 'new' object, I define for it a list of available parameters, which will be then used as that object method. So, what I want is to raise a warning when I try to do something like 
my $o = Foo->new(); #create new object
$o->Available_Param_List(["one", "two"]); #methods that should be avai
+lable to $o
$o->one('this will work ok');
$o->nope('this should print a warn on saying that nope is not availabl
+e for $o');

I want to avoid things like passing the var name to the constructor function or things like that... Thats why I been thinking that *maybe* there was a way to know the name of the variable that called to a package.
