Description:
Perl module for comments that do more than just sit there
Smart::Comments is a Perl module that implements "intelligent" comments that can aid in debugging and tracking program execution flow. They can report the value of a variable, track the progress of a loop, and verify that particular assertions are true. . Best of all, when you're finished debugging, you don't have to remove them. Simply commenting out the "use Smart::Comments" line turns them back into regular comments. Leaving smart comments in your code is smart because if you needed them once, you'll almost certainly need them again later.
