Also ask why no one used type specifier, they are possible since Python 3.0 ? Because it is the wrong way for Python. That's an example of how perceptions differ. In my list, everyone(*) uses them - MyPy, MicroPython, etc. Even more should use them (any JIT module, which are many), but sit in the bushes, waiting for a kick, like PEP484 provides.

It's OK that type hints are only to assist the programmer. PyPy's FAQ has an explanation of why type hints are not for performance. http://pypy.readthedocs.org/en/latest/faq.html#would-type-annotations-help-pypy-s-performance
