When setting up a function that takes a py::function as an input argument AND which lets that argument default to nullptr or py::none(), that function cannot be used from Python with default arguments.The workaround is to use py::object and just work with it as if it were a py::...

The model can choose to call a function; if so, the content will be a stringified JSON object adhering to your custom schema (note: the model may generate invalid JSON or hallucinate parameters). Parse the string into JSON in your code, and call your function with the provided arguments i...
If we take a closer look at the output, we observe that fun() of derived class is called and default value of base class fun() is used. Default arguments do not participate in signature of functions. So signatures of fun() in base class and derived class are considered same, hence the...
For argument matching, a function withndefault arguments is treated asn+1 separate functions, each with a different number of arguments. The ellipsis (...) acts as a wildcard; it matches any actual argument. It can lead to many ambiguous sets, if you don't design your overloaded function...

Any references to previously declared arguments must be visible in the text of validation functions and default values. To ensure code transparency, do not use functions that interact with the function workspace. Specifically, do not use nested functions or any of the functions listed in the follow...
