Formerly known as "AS3 Data Structures For Game Developers", the package contains parametrized classes that allow programmers to easily implement standard data structures like linked lists, queues, stacks or multi-dimensional arrays. The result is somewhere in between the C++ STL (Standard Template Library) and the Java Collection framework.

ds supports the following Haxe compilation targets: -swf, -js, -neko, -python, -php, -cpp, -java, -cs.
The ActionScript 3.0 build is no longer maintained. You can download the latest release here (v1.39) or compile yourself using the sample script found in tools/swc/.
-D generic
Enables generic classes (adds @:generic meta). Nice performance boost for static typed platforms (Flash/C++ only, Java is not supported right now).
-D alchemy
Enables fast virtual memory for FP10+ ("alchemy memory"). Extra performance for Flash.
