But it’s customizable, that’s the point. What happens when you remove an element from a dynamic array? I don’t even know where to look in the source code to find out and if I want to change something I can’t. Do dynamic arrays resize memory when you remove elements? Maybe I don’t want that. Maybe I want to grow the array at different intervals, can’t do that either.

I know this is very fringe but I personally needed to customize dynamic arrays to escape that thread safety thing and when I couldn’t I had to make my own array wrapper class which I would have preferred to be a record in many instances, which I can do now. If nothing else it saves me lots of Create/Free calls in countless functions. Pretty good news.

If I actually made a competent implementation (which I’ll do later) dynamic arrays are possibly made redundant even, or close to it (providing the FPC RTL had something like them included).
