Right now, does an ArrayAccess object work with array_slice()? If so, then [2, 5] syntax would be just some nice syntactic sugar. If not, then it becomes a powerful new feature, and implementing it on normal arrays and strings becomes just a matter of consistent syntax. Personaly I kinda like it, but I know I'm not the one coding it. :-) -- Larry Garfield AIM: LOLG42 larry@garfieldtech.com ICQ: 6817012 "If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it." -- Thomas Jefferson
