No, afraid not. Function capacity is not an analogue of

It's exactly the same.
But in D capacity is affected by other things.
auto a = new int[20];
auto b = arr[0..10];
//can't now append to b without re-allocating or using
assumeSafeAppend.
Perfect opportunity to inject my newly-discovered issue with
capacity:
void main()
{
auto a = new int[20];
foo(a);
//can't now append to a
}
void foo(const(int)[] p)
{
p ~= 42;
}

I don't understand what's counterintuitive here. Slices are just
pointer and length, everything else is global state.
