I don't know what Don had in mind, but multi-dimensional slice is ugly. should be A[ a..b, c..d, e..f ] but currently you have to do something like A[ [a,c,e]..[b,d,f] ]. Or A[a..b][c..d][e..f] and bend over backwards to avoid creating too many temporary proxy objects. Also you'd like to be able to mix and match slices and indices like A[ a..b, 3, e..f ]. Also a basic built in multi-dim array would be nice. I think most of the time when people make a new T(10,20) they don't really want 10 arrays of length 20, each of which can be individually resized (and must be if more capacity is needed). They want one array with size 10 x 20. --bb
