This really annoys me. I have to store the literals in char[] and then make a char*[] from them. It would be better if a simple array of string literals could be used. It would also require less data space because string literals could be merged by the compiler.

I don't know why PyArg_ParseTupleAndKeywords would ever modify the keywords array so it makes absolutely no sense to me for the array not to be const char*[].

In all cases I have seen PyArg_ParseTupleAndKeywords being used string literals were converted to char* (dropping const) which is far far worse than inefficient code.
