I can't speak to the usefulness of Perl::Tags (I use ctags myself, but I don't currently use any tags for Perl), but as for the test failures, they look harmless. Everything should go okay if you do a "notest install". I've filed a bug report on rt.cpan.org about the failing tests.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
