py-cython: updated to 0.27.2
0.27.2:
Bugs fixed
----------
* Comprehensions could incorrectly be optimised away when they appeared in boolean
test contexts.
* The special methods ``__eq__``, ``__lt__`` etc. in extension types did not type
their first argument as the type of the class but ``object``.
* Crash on first lookup of "cline_in_traceback" option during exception handling.
* Some nested module level comprehensions failed to compile.
* Compiler crash on some complex type declarations in pure mode.
* ``std::unordered_map.erase()`` was declared with an incorrect ``void`` return
type in ``libcpp.unordered_map``.
* Invalid use of C++ ``fallthrough`` attribute before C++11 and similar issue in clang.
* Compiler crash on misnamed properties.
