A small cython class to show that Cython @property is problematic with rlcompleter.

See python/cpython#112821

make
cd test ; python3 test1.py

throws the RuntimeError.

Completion is also broken in repl:

>>> from mytest import A, B
>>> b = B()
>>> b.size
42
>>> b.<TAB><TAB>
b.name  b.size
>>> b.size = 0
>>> b.<TAB><TAB>
# no completion
