I am in the process of writing my question requesting a clarification of this top voted accepted GIS SE answer - Using Geohash for proximity searches and I have a pythonic attempt as an MCVE. Is that on topic here because it also needs Cython to wrap the C library - geohash-int. There are several steps and I have taken care to illustrate in my MCVE which step points to which comment in the accepted answer. Is that on topic or will it be classified as "too broad" ?
My only concern is that the question maybe too long winded and whuber's concerns in this answer maybe popping up - How much code is appropriate for an answer?
The question will provide a python script to illustrate the problem and the Cython wrapper of the C library. If the Cython wrapper is unnecessary and merely the python script is adequate then we can address the question as psuedo code(but with the Python script) without actually running it.
