5. There are two problems with Python's C API which will become apparent if you
use a compiler other than MSVC, the compiler used to build pythonNN.dll.
Note that the order of items might be different according to the version of
Python used.

It's also possible to write your own decoders and encoders to support
more types. Pretty-printing of the JSON strings is also supported.
