Hello fellow monks!
I need an efficient way to determine which constants are given as arguments in a subroutine. Each constant will act as a switch later in some package. Here is some code: 


package MyPackage;

use constant {                         
     SCROLL_X = 1,
     SCROLL_Y=2,
     FLOW_X=3,
     FLOW_Y=4,
     ## and many more ... Let's say we have 20 constants

};
## this sub will tell us which constants are given, 
## and maybe in some other part of the package  other subs ## will kno
+w what to turn on and off};
sub which_constants {#??? }

In "main" this subroutine is given some of the constants above:

 
MyPackage->which_constants(FLOW_X,SCROLL_Y);

[download]

In short, what are the approaches for sophisticated constant management in an OO environment!

Thank you!!!
