As a Perl programmer on Windows, I've often had moments of supreme frustration. I can't use SSH or SFTP from Perl, and I can't use some of the mail handling modules. When I got started back in the early years of the century, I couldn't even use CPAN; I had to compile my own Perl and accept the fact that tests just mostly had no chance of working. Over the past year or two, however, especially as I've come to rely on CPANtesters for my own modules, I've started to realize that one reason for this is the lack of dense testing of modules on Windows. (Yeah, Paul Evans had something to do with that realization, too.)
But then Gábor Szabó posted on Google+ that he hoped to make it to #20 on the Windows smoke tester leaderboard. (As of today, he's at #19 - congrats!)
Wait. There's a leaderboard?
