Yes, I had seen them, and they are both valid criticisms. There are more examples in v2. The syntax matches exactly the syntax used for specifying segments of number line in algebra classes. If this goes into the language, people who are writing nonlinear number systems would have to decide whether to support it or not and if so how; that goes w/o saying the inspiration for it, along with its companion piece on an implied grep in certain hash accesses, is a way to ease slicing of "traditional" multidimensional arrays. %Center_of_4x4x4_cube = %FourCube{/[2,3] [2,3] [2,3]/} ; That's an old-fasioned fake multidimensional array, of course, not one of these new creatures. -- David Nicol 816.235.1187 [EMAIL PROTECTED] "The most powerful force in the universe is gossip"
