It starts with:
int[] original;
original.reserve(5);
writeln("orig cap: ", original.capacity); // 7
writeln("orig len: ", original.length); // 0
Further down says: "But to discuss behavior we'll need some
elements."
and immediately proceeds with code accessing original where no
data has been added:
auto slice = original[1..$];
writeln("slice cap: ", slice.capacity); // 6
writeln("slice len: ", slice.length); // 2
original[0]++;
slice[0]++;
slice[1]++;
writeln("orig: ", original); // [1, 2, 3]
I don't know where the [1,2,3] comes from. The first
original[1..$] will crash. Maybe you are forgetting the actual
initialization of original with data?
