Call is the work a Script runs when Lua invokes a reflected method, property, or constructor. The script owns the call and deletes it after call() returns. Application code does not construct a Call; the binding closures do.
call() performs the invocation and returns the result as Any. A thrown std::exception is stored as an error: hasError() is true and errorMessage() holds the text. rtype() is the Reflex result type, or a null pointer when the call has no result to push.
