/*
 *  call-seq:
 *     enum.any? [{|obj| block } ]   => true or false
 *  
 *  Passes each element of the collection to the given block. The method
 *  returns <code>true</code> if the block ever returns a value other
 *  than <code>false</code> or <code>nil</code>. If the block is not
 *  given, Ruby adds an implicit block of <code>{|obj| obj}</code> (that
 *  is <code>any?</code> will return <code>true</code> if at least one
 *  of the collection members is not <code>false</code> or
 *  <code>nil</code>.
 *     
 *     %w{ ant bear cat}.any? {|word| word.length >= 3}   #=> true
 *     %w{ ant bear cat}.any? {|word| word.length >= 4}   #=> true
 *     [ nil, true, 99 ].any?                             #=> true
