Branched dynamic arrays are MUCH slower than rectangular/cubic/etc. static arrays - and this is a severe limitation for anyone wanting to work with large amounts of data (e.g. game maps). Of course I could work around this by calculating the positions manually using x*width+y, but I'd like to know the reason why this limitation was put there in the first place, and what's the reasoning behind it. No other compiled language that I used (C/C++/Delphi) has such a limitation.
