I don't like "PyConstObjectArray" or any other name. I will just obfuscate the C code. "PyObject * const *args" should be clear for every C programmer, but if I see "PyConstObjectArray" I need to search the definition of it in the header files. And it is easy to make a mistake by using "PyConstObjectArray *" instead of "PyConstObjectArray" since complex types usually are passed by pointer in C.

If you prefer, "PyObject * const *args" can be written as "PyObject * const args[]". This is an identical syntax, but the latter form is used more rarely.
