Description Sven Efftinge CLA 2011-09-06 03:35:28 EDT 
A closure with one arg is a very common case. Therefore it's interesting to have a special short cut syntax for them.

The syntax is [ my-expression-using-it ], i.e. there is one implicit variable bound to the variable name 'it'.

So you could write :

newArrayList( 'aaa' , 'a', 'aaaaaa').sort( [length] )
