Description

The following code, derived from example4_custom_functions.py errors, since the parser can't find the custom function.

    def times(value):
        return lambda array: list(map(lambda item: item * value, array))

    query = "true and times([1, 2, 3])"
    options: JsonQueryOptions = {"functions": {"times": times}}
    print(jsonquery(data, query, options))

Peeking at the code, it would seem that the custom arguments passed on the higher lever evaluation are not passed to recursive evaluations, and thus the function is not found.

Research direction

Start with example4_custom_functions.py and reproduce the failure using the nested condition true and times([1, 2, 3]). Trace how custom functions are passed into recursive evaluations. Done means the provided times function is found and the query evaluates successfully.
