short any_tail (CESI_Callback_t f, ESI start_ptr);

Checks whether any element in the list has some property.

any_tail is similar like all_tail, except further processing of the list will be stopped if f returns TRUE instead of FALSE. In other words, it returns TRUE if and only if the callback function f returns TRUE for at least one expression in the tail of expressions indexed by element_ptr. any_tail is very useful to check whether any element of a list possesses some property. Assuming the same assumptions as in the example given with all_tail, the following call will check whether any element of the list is a positive integer:

    is_any_positive_integer = any_tail (is_positive_integer, start_ptr);
