Re: [Vala] support for Python C API

[Arc Riley <arcriley gmail com>]

What does it not support, then, out of the PyType slots:

   - tp_name - can the name be set manually, or must it mimic the Vala name
   - tp_print
   - tp_repr - this is extremely important for frameworks
   - tp_as_number
   - tp_as_sequence
   - tp_as_mapping
   - tp_hash
   - tp_call
   - tp_str
   - tp_getattro
   - tp_setattro
   - tp_as_buffer
   - tp_flags
   - tp_doc - essential - does this copy valadoc or have another method to
   set it
   - tp_clear
   - tp_richcompare
   - tp_weaklistoffset
   - tp_iter
   - tp_iternext
   - tp_methods
   - tp_members
   - tp_getset
   - tp_base - can it be subclassed
   - tp_dict
   - tp_descr_get
   - tp_descr_set
   - tp_dictoffset
   - tp_init
   - tp_alloc
   - tp_new
   - tp_free
   - tp_bases
   - tp_subclasses
   - tp_weaklist

Some of these are redundant or depreciated in use, but a vast majority of
them are essential.

Does it convert to bytes/unicode properly?  Does it check the type being
passed to ensure the resulting bindings cannot be segfaulted by pure Python
code?  Does it map libgee to these datatypes or what is the method used to
pass container objects between GObject code and Python?

Most importantly, where are the docs, or at least example code showing
that/how these things work?
