Swartz asks us to stop running tests while installing CPAN modules. This a very good idea.
It is very important to make it easy for a beginner to install and work on any Perl module. And a beginner can not be expect to be able to use the results of the tests for anything useful.
We should make a default Perl not require tests to install CPAN modules, while an experience user should still be able to turn on tests.
This will make it faster, and easier for a beginner to actually do something productive and get to the aha moment.
We don't want people to feel the same way as they do with slow web pages or splash screens.
