   FYI the lxml project still uses uses deprecated functions:

   src/lxml/parser.pxi:            py_buffer_len = python.PyUnicode_GET_DATA_SIZE(utext)
   src/lxml/parser.pxi:            c_len = python.PyUnicode_GET_DATA_SIZE(text)
   src/lxml/python.pxd:    cdef Py_ssize_t PyUnicode_GET_DATA_SIZE(object ustring)
   

   Compiler warnings on Python 3.11:

   Thank you for reporting.
   I reported it to lxml. https://bugs.launchpad.net/lxml/+bug/1973155

   I tried to fix it but I don't have enough skill to write compile-time switch in Cython.
   If it is difficult to fix it soon, I will resurrect PyUnicode_AS_DATA and PyUnicode_GET_DATA_SIZE as dummy function that just raise an exception.

   I wrote https://github.com/gevent/gevent/pull/1872/files which has conditional code depending on the Python version.
