not that kind of language, it does not even come with integer types or "plus" operator by default.. they do give an example of

    define { minutes { dequote choose {minutes} {} = {:} <-[characters] } } { minutes {1:23} }

    "1:23".split(":", 1)[1]

    def minutes(x): 
        return x[1:] if x[0] == ':' else minutes(x[1:])
    minutes("1:23")
