关于dmkit中func_val自定义函数

经过阅读源码，func_val函数时c++写的吧？然后请问下，func_val可以用python写吗？如果不能用python写，那如何用python实现这种复杂的对话流程尼？可以给些参考文件代码吗。
ps：如果不能用Python写，是不是意味着当意图和词槽识别后，需要自己构造所有的逻辑函数，来实现复杂的对话流程？

Start by locating func_val in the dmkit source and checking how its C++ implementation is invoked after intent and slot recognition. Determine whether Python integration is supported, then document the supported workflow and point to reference files or examples for implementing complex dialogue flows.
