I&#x27;m not glossing over anything, I was relating my experience, and I&#x27;ve had very few issues.<p>I don&#x27;t even see what your complaints have to do with the Python2&#x2F;3 transition.  Python isn&#x27;t a statically typed language, so obviously Python3 isn&#x27;t going to fix badly written code with type errors.<p>Regardless, if Python2 to Python3 has been a mess, clearly Perl5&#x2F;6 has been an even bigger mess because they haven&#x27;t even managed to release the interpreter, much less start moving to it.
