Wouldn't it be nice to have GeoJSON data deserialized as GeoJSON objects in pymongo, just like bson.ObjectId or datetime.datetime instances?

Consider following code:

import bson
import datetime
import geojson

d = datetime.datetime(2016, 1, 1)
o = bson.ObjectId('0123456789ab0123456789ab')
g = geojson.Point([1, 2])
print(type(d))
print(type(o))
print(type(g))

data = bson.BSON.encode({
    'a': 1,
    'd': d,
    'o': o,
    'g': g
})
decoded_doc = bson.BSON.decode(data)

print(decoded_doc)

print(type(decoded_doc['d']))
print(type(decoded_doc['o']))
print(type(decoded_doc['g']))

decoded_doc prints as:

{'a': 1, 'g': {'type': 'Point', 'coordinates': [1, 2]}, 'o': ObjectId('0123456789ab0123456789ab'), 'd': datetime.datetime(2016, 1, 1, 0, 0)}

where g is a dict. It could be nice to get a GeoJSON object.

This could rely on already existing GeoJSON library: https://github.com/frewsxcv/python-geojson.

Unless adding this kind of dependency is an issue.

I realize that this library might not have reached required quality / stability. On the other hand, duplicating it inside pymongo would be a shame.

I figured pymongo's bson might be the good place for that rather than application code.

Just an idea. Feedback welcome.
