On the &quot;Ruby Kaigi&quot; presentation (<a href="http:&#x2F;&#x2F;www.atdot.net&#x2F;~ko1&#x2F;activities&#x2F;2015_RubyKaigi2015.pdf" rel="nofollow">http:&#x2F;&#x2F;www.atdot.net&#x2F;~ko1&#x2F;activities&#x2F;2015_RubyKaigi2015.pdf</a>), Koichi Sasada states that Matz doesn&#x27;t like the automatic compilation of source files a la Python, which automatically generates .pyc files.<p>Why is this?  I understand the inconvenience of having lots of compiled files in your deployment structure but I guess having a static compile phase would be worse.  Any opinions on this?
