But this doesn't means that with this chunks of codes, that come from other modules to avoid requisites, I'm not adding new things! Generally this chunks of codes are revised, fixed and upgraded.

But note that here our policy of development is to always create a system not much dependent of others. 1st because our enverioment that we develop need to be easy to install, 2nd because it need to be portable for many OS, and dependecies make this harder.

For example, XML::Smart has his own parser, XML::Smart::Parser, that is a upgrade and fix of XML::Parser::Lite. Why that? Because XML::Parser, the main XML parser for Perl, uses 26 modules. But the biggest problem is not to load 26 modules, but this modules come from a lot of different distributions (XML::Parser need: URI, HTPP, LWP, libwww...), that need much more things to be installed. So, 1 dependency generally means more sub-dependencies.

History also shows to us that big dependencies make the probabiblity of bugs bigger, and is harder to fix them, but the biggest problem is the probability to have incompatibilities in the future with new versions. I know that, since I try to use less dependencies as possible, and I had this problem in less than 1 year with 2 modules.
