      Description

      With regards to a thread in the groovy user list here:

      http://groovy.329449.n5.nabble.com/How-to-access-first-10-characters-even-if-string-only-have-5-td4456146.html

      A take( n ) method would be a really useful addition to the Groovy codebase

      It is assumed it will work similar to other languages, in that:

      def a = [ 1, 2, 3 ]
      
      assert a.take( 0 ) == []
      assert a.take( 1 ) == [ 1 ]
      assert a.take( 4 ) == [ 1, 2, 3 ]
      

      The method should work for Collection, String, Map and lazily for Iterator, Reader and InputStream
