Why most of the CPAN/core modules lacks comments(definitely it has man pages)?. Any particular reason for it.
The reason for asking this question is, as and when I use a subroutine from an external module(can be core module or downloaded from CPAN), I would go and see how the subroutine was implemented in the code by the author, to get to know the good/efficient practices, but many a times because of lack of comments I have gone to other modes like using a debugger, copying only that subroutine and putting some debug messages to it, etc. It would be excellent if it comes with sufficient comments(from a learner point of view).
I believe that I have asked nothing wrong here.
