What was the version string experiment trying to achieve?

And how, exactly, are these version numbers used by other code? I imagine they are checked to make sure that a module has certain capabilities that it needs. But how does that actually get implemented in practice?

Also, what is the thumb rule for creating new versions? If I fix a typo in a comment, should I increment the version number? I'm guessing no. But when should I?

$PM = "Perl Monk's";
$MCF = "Most Clueless Friar Abbot Bishop Pontiff Deacon Curate";
$nysus = $PM . ' ' . $MCF;
