I implemented my own DynamicArray struct which behaves more like
I want it to and is still giving me all of the benefits that I
want from dynamic arrays.
Having no clear ownership for the array is not something I am
willing to accept. Same thing for the non-deterministic copying
and destruction behavior for the elements. That's the kind of
thing which looks convenient at first, but will create many small
performance problems. Once those add up to a big problem, it's
incredibly frustrating to fix because your slow downs are from
all over the place.
I don't anticipate that I will ever run into a situation where I
want to append to a range without caring about whether it
allocates and copies or not. If I want to append to a range, I
will write the extra line to create a copy manually.
Because of that I don't need the syntactic ambiguity of treating
a range the same as an array.
