/* Capsule objects let you wrap a C "void *" pointer in a Python
object. They're a way of passing data through the Python interpreter
without creating your own custom type.
Capsules are used for communication between extension modules.
They provide a way for an extension module to export a C interface
to other extension modules, so that extension modules can use the
Python import mechanism to link to one another.
