Syntax

some? ( fun As Name, _
        list As List ) As Boolean 

Argument	Type	Description
fun	Name	The name of the function to apply. The function must accept a single "Any" parameter, and return a Boolean .
list	list	List of arguments, to which the function will be applied.

Example 1

Intent >some?(:empty?, {{1}, {:a}, {}, {:b}}) 
--> True 

In this example, the third element of the input list is empty, and therefore the empty? function returns True for it.

Example 2

Intent >some?(:empty?, {{}, {:a}, {}, {:b}}) 
--> True 

In this example, more than one of the list items matches the empty? predicate.

Example 3

Intent >some?(:empty?, {{1}, {:a}, {2}, {:b}}) 
--> False 

Here, none of the list items matches the empty? predicate.

Example 4

Intent >some?(:even?, {1, 2, 3, 4, 5}) 
--> True 

Here, 2 of the 4 list items causes a True return for the even? function.

Example 5

Intent >some?(:even?, {1, 3, 5, 7, 9}) 
--> False 

Here, none of the list items is even, so no matches are found.
