Of course, this leads to the question of "Why are you changing the value of a constant?" Or, "Why are you using the same constant name twice?" I mean, either it's constant for the whole bleeping world or it's not!

If you find you absolutely must use the same constant name twice for different values, you kinda have two options:

  1. Use different modules. I highly recommend this option.
  2. Use array constants. 
    use constant FOO => [qw(a b c)];
use constant FIRST => (0);
use constant SECOND => (1);

print FOO->[FIRST], $/;
print FOO->[SECOND], $/;

Personally, the second is very ugly and prone to error. But, TMTOWTDI, I guess.

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.

Please remember that I'm crufty and crochety. All opinions are purely mine and all code is untested, unless otherwise specified.
