I agree, but so far I am not able to modify/improve the language. And an ArrayBuilder isn't meant to replace dynamic arrays, it's just a way to build them faster, "patching" what I perceive as one of their problems.

My libs are meant to improve std libs, if/where/when the compiler can't be modified. They are un-standard but they are largish libs anyway, and I'm developing them doing my best :-)
