Omid:
arr = [[1,2,3,4,5,6],[7,8,9,10,11,12],[13,14,15,16,17,18]]
I want to obtain a subarray like
assert(arr[][0] == [1,7,13]);
This gives a range, not an array, so if you want an array, you
have to call std.array.array later:
http://dlang.org/phobos/std_range.html#transversal
assert(arr[1][] == [7,8,9,10,11,12];
Just use array[1]. Or array[1].dup is you want a copy.
assert(arr[0,2][1] == [2,14]);
Enumerated indexes are not supported, so you need a iota + filter
+ transversal + array.
assert(arr[0,2][0..3,5] == [[1,2,3,6],[13,14,15,18]]);
This requires a iota + filter + chain + array, or something like
that.
If you don't want to do all this, you have to write your slicing
and dicing array struct :-( Someday it will probably be present
in Phobos.
