Function interp_recall 

fn interp_recall(
    positional: &[RValue],
    named: &[(String, RValue)],
    context: &BuiltinContext<'_>,
) -> Result<RValue, RError>

Recursively call the current function with new arguments.

Recall(...) finds the currently executing user function from the call stack and calls it again with the supplied arguments. This is useful for anonymous recursive functions that don’t have a name to call themselves by.

@param … arguments to pass to the recursive call @return the result of calling the current function with the new arguments
