* Add PRECALL_FUNCTION opcode. * Move 'call shape' varaibles into struct. * Replace CALL_NO_KW and CALL_KW with KW_NAMES and CALL instructions. * Specialize for builtin methods taking using the METH_FASTCALL | METH_KEYWORDS protocol. * Allow kwnames for specialized calls to builtin types. * Specialize calls to tuple(arg) and str(arg).
