It is not natural to write : %my_fruit_set = ( 1 => 'orange', 2 => 'lemon' ); but it is natural to write : @my_fruit_set = ( 'orange', 'lemon' ); I don't want to have to deal with keys of hashes because my set elements don't care about them ! so, I want new functions to manipulate arrays. then, when manipulating arrays, without speaking about sets, you often need in/union/intersection functions, even if arrays have duplicated elements or if they are ordered. Well, in fact I don't understand why you don't think that union/intersection/difference are not usefull functions for arrays ? Gael,Thread Previous | Thread Next
