But the Python 2 development community a) has announced a specific date for end of life (January 1 of next year), b) had communicated the intention to sunset Python 2 in favor of Python 3 for years before the specific date was announced, c) is no longer applying anything but critical bugfixes to Python 2, and d) has collectively moved to developing Python 3. None of these are true of Perl 5/6. Alternatively, if we're going to look for analogies in other languages instead of listening to statements from the Perl 5 community themselves, let's make an analogy to C and C++. Despite C++ having been a mature, usable language for decades, people are still using and developing C compilers and libraries.
