API : constness ?

[Benoît Dejean]

i don't understand why the ANSI const keyword is never used in the API. eg

PyArg_ParseTuple( PyObject *args, char *format, ...)

should be

PyArg_ParseTuple( PyObject *args, const char *format, ...)

or 

PyArg_ParseTuple( const PyObject *args, const char *format, ...)


so i spend my time casting my format argument ...
