Hi monks, I'm trying to access a .pm file containing constants (as in "use constant XX => 1;") from two other files by putting a "use Constants" at the top of each. However, one of the two files uses the other one as well and Perl complains about whichever one uses the constants second. i.e. if in file A.pm I have: 
use B;
use Constants;

[download]
then the interpreter complains about constants in A but not B. if I have instead 
use Constants;
use B;

[download]
then it complains about constants in B. Questions:
1) What gives?
2) Is this the best way to use constants across multiple files?

UPDATE: I think export will do it. Thanks!
